If congress never declared war then how are all the dictator events taking place?

They did declare war on . But the real results are from a rule that allows the president to activate troops for 90 days without congressional approval. At which time congress has to authorize their stay, or they come home. It is so expensive to activitate troops and to bring them home that congress is not likely to deny authorization. Plus, we had already created a mess, and now we need to clean it up. Congress recognizes that unlike the American public. We may have made a mistake in going, but we can't change the fact that we did. Now we should own up to our actions and follow through.
