Murphy said:

“If Kosovo were to happen in 2017, so we’re out of Afghanistan, I don’t want to get into a position where we would say, post-Iraq, post-Afghanistan, ‘we couldn’t do another Kosovo’.”

“It’s important to make that argument. I’m not trying to nudge things in favour of another military intervention anywhere but you shouldn’t let the residual real anger that there is about the Iraq war defeat the pride that we have in what we did in Kosovo.”

“How do you stop one-and-a-half unpopular wars – with Iraq certainly being unpopular and Afghanistan at least partly there – creating an unpopular concept? The unpopular concept is that you have a responsibility beyond your own borders.”

“We sat and watched what happened in Rwanda as an international community. Everyone said ‘never again’ after the previous genocide. How do you prevent people’s genuine fury about Iraq stopping us from ever exercising force in the future without appearing like the ‘more war’ party. I don’t want to let the anger about Iraq trump the shame of Rwanda.”

He could just as easily have spoken about Sierra Leone as about the stopping of the Kosovo genocide, another case where Tony Blair used military force to secure a humanitarian objective, ending the slaughter by the rebel RUF forces.

Of course, I take the perhaps unfashionable view that we shouldn’t be apologetic about the UK’s role in liberating Iraq from Saddam Hussein, or in deposing the Taliban in Afghanistan. However, I can see there is a middle ground on the left of those who opposed Iraq but need to be persuaded not to jump from this to a blanket rejection of interventionism that would rule out a future Sierra Leone or Kosovo-type operation. I welcome Jim’s effort to try to persuade those people not to reject the use of force outright.

This morning I asked people on Twitter what they thought I should write about today. The first reply flew back from Jeremy Corbyn MP, who I had not realised was hanging on my every tweet. He asked me to write about “a foreign policy [based on] human rights and international law not arms sales and intervention”.

Being an ideological rather than cynical sort I actually share Jeremy’s concern for a “a foreign policy [based on] human rights and international law” but would probably delete the word “not” and insert the word “and” so it reads “a foreign policy [based on] human rights and international law [with the first trumping the second as a criteria] and arms sales [to carefully judged countries] and intervention”.

Here’s why:
• Without intervention, how do you ultimately guarantee human rights and international law? Moral persuasion and pressure and demonstrations outside embassies will take you only so far, and with the worst dictators only the timely arrival of warships, military aircraft and troops – or the threat of it – will stop them killing or torturing their own people.
• What happens when international law stops you from taking action to safeguard human rights? For instance when a human rights abusing country like China uses its veto on the UN Security Council to block intervention in another authoritarian country.
• Does Jeremy want us to stop selling arms to everyone? We can all agree with the current UK export control criteria that military equipment can’t be sold to countries where the UK Government believes there is a risk it will be used for “internal repression or external aggression”. But don’t democracies have a right to buy kit to defend themselves? Don’t less-unpleasant regimes have a right to defend themselves against bigger heavily armed neighbours? This is why we and other Western nations have sold arms to Kuwait, Saudi Arabia etc. These may be despotic regimes (and I’d like them to be overthrown and replaced by democracies, or better still transition peacefully to democracy) but compared to some of their neighbours they look angelic, and they have a right under international law to defend themselves against threats from Iraq (in the past) and Iran (now)- which they can’t do without equipment. Sometimes the UK gets it wrong and we sell kit that does end up being used for “internal repression” but there are types of defence equipment like minesweeping boats, submarines or air defence systems and missiles that have no possible internal or offensive use, and are for territorial defence against aggressors, but that Jeremy would subject to a blanket ban (the net result of which would be they would be bought from China, France or Russia instead).

There’s also moral grey areas that Jeremy’s simple formula can’t deal with (in fairness he was trying to summarise his position in a 140 character Tweet!).

There’s no universal consensus on who the heroes and villains are in global geopolitics. Jeremy is a big fan of Cuba and Venezuela. I’m not. I’d like to see the human-rights abusing regimes in both countries ousted. I’m not sure where his support for them sits with his apparently absolute position on human rights.

And sometimes you have to engage with unpleasant regimes to try to get them to reform, to detach them from alliances with even more unpleasant regimes, or to get them to behave in a less threatening way.

Which brings us to the current slaughter in Libya.

I believe Tony Blair was right to engage with Gaddafi in the mid-part of the last decade. There was no prospect then of regime change in Libya. Engagement ended Gaddafi’s WMD aspirations. Thankfully it means the current bloodbath is not being exacerbated by the use of chemical weapons against his own people as Saddam did at Halabja against the Kurds. If the West had not engaged with Gaddafi he would probably have those weapons and be mad enough to use them. It is odd that some of the same people criticising Blair and Bush for finding a peaceful way to get Gaddafi to give up on developing WMD opposed the alternative method used to tackle the same perceived problem in Iraq. Presumably they think we should neither engage nor intervene, but just moralise and hope for the best.

And as for now, with regime change possible and perhaps even imminent, and Gaddafi appearing to be intent on causing the maximum loss of innocent life during the process, I think there is a case for an early return to the liberal interventionism that characterised Blair’s premiership.

The person who has been boldest on this is former SDP Leader and Labour Foreign Secretary Lord Owen (I know that’s an argument against it for many Labour people but let’s address his proposal, not the history of the man making it). On Radio 4 he has called for a UN-sanctioned no fly zone to stop by force Gaddafi’s ground attack aircraft and helicopters gunships from bombing and strafing his own people. There are plenty of NATO bases within flying distance to make this work. If the UN Security Council can’t do it because of a Chinese or Russian veto, NATO should instead.

This is a moral imperative. We have the power to save lives so we should use it. We have the power to hasten regime change from despotism where there is popular demand for it and where it is a real possibility. And it is a geo-political game-changer which would transform the West’s reputation in the Arab world from the invaders of Iraq, to the humanitarian defenders of the Libyan people.

I hope that Labour will now make the running on calling for this, not leave it to Lord Owen. The alternative to intervention is warm words and treating the bloody transition to freedom in Libya as a spectator sport – and ultimately more dead civilians. The time for “another Kosovo” that Jim Murphy talked about is already here, now.
