It resonated every time we had an undeclared war - Vietnam, Korea, Iraq. Only an official Declaration of War by Congress has united the nation as it did in WW II. A lesson for future Presidents.
The gulf of Tonkin resolution was the Vietnam declaration of war, and was passed by the Democrats.
The voting of war credits for Iraq was the Iraq declaration of war, and was passed with broad bipartisan support. That sneaky Bush, arranged for the vote to take place just before the election and slimey members of the legislature were unwilling to vote against it so close to an election.
Congress passed war spending for Korea too.
We have nice parting gifts.
I submit it was the suprise attack by Japan that unified the nation, rather than the formality of the declaration of war.
Still the communists in the US were upset that the US didn’t get engaged more quickly in Europe to take the pressure off the Soviet Communists. They were more than willing to have more US soldiers killed to help out Joe Stalin.
