Did the (read: the) 9/11 attacks of 2001 embolden people to more freely speak out against U.S. foreign policy?

I've heard many things about how 9/11 changed the face of the world, and one of them was that people realized it was safe to speak out. In essence, that violence and terrorism are always wrong, because they are used to make those on the receiving end do what the aggressors want. <br><br>What happened to Europe after WWII was another instance of this, and this is probably why the U.S. became more insistent on defending Israel from the Arabs. <br><br>In general, I appreciate emboldening people to speak out against injustice. <br><br>For context I was born in 2002 and I have no idea what things were like before the 9/11 attacks in terms of U.S. foreign policy. But I do know that this is the first time I've ever heard someone (Ileana Ros-Lehtinen, who is on the House Foreign Affairs Committee) talk openly about the fact that the U.S. was the one to blockade Cuba for decades.
