A declaration of war was needed the day after 9/11. Because 9/11 was simply another Pearl Harbor. But Bush II decided on a weird nation-building police action instead. Say what you want about FDR, but we needed an FDR the day after 9/11. We sure didn’t get one.
I don’t know why you’re complaining? WWII was the last was the last war declared by Congress. You are ignoring that President Bush went before Congress and the UN, while that arrogant pos occupant of 1600 Pennsylvania Ave just does as he pleases
