Will I be arrested if I often criticize the United States?

You are right to scold the United States. They plunder resources all over the world, kill and set fires, bully weak countries, provoke wars, and subvert other countries. Of course you can scold them, but don't promote terrorism. You can also praise the Arab fighters who died fighting against the American invaders, and you can praise Lao La and Lao Sa for their spirit in fighting the invaders, but you cannot praise their attacks on civilians, so you can change your words, such as the plane incident, you can say : "The heroic Arab war gods sacrificed their lives for their families, motherland, freedom and faith to fight against the devil of American hegemony to the end. With the fury of revenge, they dealt a devastating blow to the economic center of the United States." But don't just praise it. They crashed into buildings and attacked civilians because it would appear low-level, would not cause psychosis, and might also be illegal. Often just another word will suffice.
