Why do these arguments always kick off?
We're all friends here. Besides I think saying things like we Americans/British helped you do X or whatever is completely beyond your right to do so. If neither of you have been involved in a conflict fighting for the other then shut up.
Even if you have, I very much doubt that you fought in WW2 of the Falklands so there is no way you can throw these accusations around, and at the same time proudly add yourself to the group of people that risked their lives to do the other a favour.
A bit of patriotism is fine but shouldn't lead to insulting the other, especially in a nice, friendly forum like this.
Now kiss and make up
