Events like this have often been used as trigger to implement measures that were already planned. The nazis did that a lot (Reichstagsbrand, Kristallnacht), You could argue that Israel used the October 7 attacks to accelerate efforts to get rid of the Palestinians. Bush/Cheney/Rumsfeld used 9/11 to invade Iraq which they had wanted to do long before.

I am definitely worried what Trump and republicans will do as a response.
