And in December 2016, the FARC hand over their weapons.

I remember it was actually my last day at work, the day that the FARC handed over the last AK-47 in northern Colombia.

I was standing there, it was my last day at work as police commissioner, and there was a man, I think an Argentine, from the UN verification mission who had been in many places around the world, and he said, you know, Commissioner, I've never seen anything like this, because the FARC would... kind of marched into this camp in formation, and the soldiers were all standing there, and the FARC handed over their weapons to the UN, and everything was like textbook.

According to Sergio, you cannot fully compare the war in Ukraine with the one in Colombia.

It's a very different thing to end an internal armed conflict where in the end you're talking about citizens of the same country.

You're all going to end up being part of the same thing.

And the concept of war living together if you like, but if you've been invaded by your neighbor, you're in a slightly different place.

So I think in that sense, there are many things here that don't apply.
