Shakran you are so wrong about the Vengence weapons it isn't funny. June 13th, 1944 was the first time a Vengence weapon was used on the British. The Brits first learned that the krauts were working on them in December 1942, which was a full year after we declared war on Germany. By this point, US troops were already fighting German troops in N. Africa. The maximum range of both the V-1 and V-2(or A-4) was 200 miles, hardly enough to reach America. The difference was that the V-2 had a slightly larger payload than the V-1. The Germans WERE working on 6 newer versions of the rocket when the war ended, however, the best only managed to double the elder rockets' range (to 400 miles) and decrease flight time to 17 minutes. So, no, the Vengence weapons had not a damn thing to do with the United States declaring war on Germany.

As to American's feelings about France, I will say this. As long as I have remembered, there has been the feeling that they are/were cowards, or what have you, thanks to their less than stellar war record since Napolean's glory days ended. It has become much more pronounced ever since they opposed us invading Iraq. Frankly (no pun intended), neither country is doing much to repair relations with one another.
I will admit that the frogs did help us greatly with our war for independence, however, I don't think it was because they were being alturistic. Rather, they enjoyed watching us being a thorn in the side of their age old enemy, the British. Fact is, we only "won" the war because we were being difficult enough that when the French and the British started warring again, the Brits just said "Fuck it, we'll deal with you later." Then you have the War of 1812, which was basically the British coming back saying "Ok, that thing with the French has died down thanks to their own revolution, we want our colony back." That didn't turn out too good for the Brits.
So then along comes The Great War, and amazingly, the Brits and French are working together! I mean, these two warred on and off for the past 1,000 years, and now, English troops are in France, fighting with the French against the Germans! WOW! All the old kings must have been turning in their graves. Basically, both sides kicked the shit out of each other, thanks to new technology and outdated tactics. They are in a stalemate, with the Germans making very, very slow gains, when the Yankees come riding in, like the calvary in those old western movies. They give just enough Umpfh to the Allied cause to drive the Hun back, who then capitulate, everyone is happy, rah rah!
Then comes Hitler, he riles up the down trodded Germans into war, and off they go. Again, the British and the French fight side by side against the Germans, but this time, the Germans are using new tech AND new tactics, while their adversaries use new tech and old tactics. Insert ass whooping here, now there isn't anyone in continental Europe to stand up to the Nazis. Battle of Britain occures. British ability to produce war supplies almost exhausted when a small bombing raid on Berlin causes Hitler to divert his bombers from factories to cities. Factories then manage to produce enough planes to help the grim British resolve to win. Invasion of Britain called off, turns sights on Russia, and proceeds to lose vast numbers of men and material in the Steppes. Declare war on the US after Pearl Harbor, Stalingrad, Kursk, D-Day, etc. Hitler offs self, Germany surrenders, that's it folks.
So, the United States kind of helped in WW1, and definately helped in WW2. France helped in ARW. Now, the French think we are stupid, well there are lots of stupid people in the US, but not ALL of us are. US thinks all French are snobs, see last sentence. Neither side is willing to budge, the end. I hope this sums up how things have developed up to this point. I think we all need a group hug.
