Good god. If we hold your logic we will be going to war every single week with a new country. Further going to war with a nuclear power is not an option, it basically means destruction of our planet, but you are promoting war for what? Because Trump Jr. met with a russian lawyer and Russian outlets wrote some fake news articles?
Also Russia didnt install a puppet into the White House. Trump was voted in by american citizens, unless Russia has been shown to change votes which there is currently no evidence of.
This whole thing is disturbing and unethical but not worthy of going to war.
