Which flag and anthem was it though?

I'm going to go out on a limb, here, and say you're joking around. Then, I'll giggle a little - but not much, because, in my opinion, what the article speaks of is more impacting today than people might realize. Then, I'll say that this means this isn't a joke, and the reality of it shouldn't be taken lightly.
My grandfather was involved in both WWII and the Korean War. He was on the front lines, shooting live footage of our boys getting shot at and blown up. He risked his life every second of every day he spent on the field. Why? Because that's what his country wanted him to do.
Personally - and maybe I'm being a tad oversensitive, here - I don't feel that it's appropriate to make light of something like this. It doesn't matter who's national anthem is being played; what matters is how people feel when they hear their national anthem.
