Governments will change, people on the top might change. The question is whether they will face any consequences for their actions. Will the US as a whole face any consequence of its actions. Like the consequences other countries face when they do the stuff America is doing right now.
Or will it be back to normal as soon as the regime changes.
Will there be any lasting effects in how the world deals with US?
Thing is Trump is not the only one in the government. Everyone from the top to the very bottom of GOP is involved in each and everything the government is doing.
Whether or not Trump faces consequences is immaterial if he is just made a scapegoat while US continues being the world bully.
