The BBC (and other media elements, but especially the BBC). The current affairs and documentary programming areas often seem to be gripped by anti-US and anti-Israel sentiment that leads to inherent bias in the way these countries are portrayed. Just watch BBC current affairs (and documentary programmes with any kind of political overtone), and just count how often you see an Israeli or an American who is left wing, moderate, secular, and tolerant. It's pretty rare. This portrayal of the US as a country full of foaming at the mouth uber-patriot warmongers creates a negative sense of 'us and them'.
Just my theory... criticsm / thoughts welcome!
On the contrary, I'd be willing to bet money that they were Bosnian Serbs, who (as do many Serbs in Serbia and Kosovo), resent NATO, (particularly the UK and USA who did most of the actual bombing) for our role in Kosovo.
I don't think the Kosovan conflict was all we think it to be. The simple fact is, before the conflict, Kosovo was a province of Serbia and had many Serbs living there, and now, it isn't, and there are none. Kosovo is virtually pure Albanian. Now that, to me, sounds like ethnic cleansing, but isn't that what THEY were accused of? Whilst I am certainly not defending Serbs, I feel all is not as at seems there at all.
I think you are right on the Bosnia thing, I couldn't work out how to describe it and was just wanting to make the point about the anti-British feeling I encountered. I actually worked with a Serb during that time, he'd moved to the UK some years before and it was quite an interesting time getting a different view of the conflict.
As to the BBC - anti-Israeli? Not sure we need to go down this path on this thread, but my viewpoint is that they are just not pro-Israel like the vast majority of US media. They don't always have rabid right-wing Americans on either, in fact I find they speak to a lot of Democrats. As an aside - next week on Question Time, as it's the one prior to the Presidential election, they have Jerry Springer on (a Democrat) and an, as yet unnamed, "prominant Republican supporter" on. DW and I mused on that one and wondered - Clint Eastwood?!
