We should absolutely refuse to recognize Russian sovereignty over Crimea. This is extremely important since President Trump seems to be inclined to do whatever Putin wants. The Russians basically invaded the sovereign nation of Ukraine and annexed an important part of that country. The United States must take the clear position that this is an unacceptable violation of international law and illegal aggression which cannot stand. How would we feel if Russia decided to annex Alaska? Would we think other countries should just accept it? What countries will Russia annex next? What if North Korea decides to annex South Korea or China decides to annex parts of Japan? The entire world must stand united against such violations of national sovereignty. This is exactly how the last two World Wars started and we must take a stand now to prevent another. Congress must do it because Trump has no understanding of history and no notion of national security other than my button is bigger than yours. God help us.
