The tactic of sanctions against Russia has proven ineffective and damaging to the regular people of Russia. It's time that the USA, and other nations started to look for other resolutions to relations with Russia. I'm not sure that inviting them for tea is exactly what is required, but it's definitely time for a round table chat.
Ultimately, the people of Russia don't have anything against the people of the United States. The people of the United States like, respect and admire the people of Russia. However, the governments of the two countries have different ideologies and they cannot get along. Having a tea would be a fun way to bring the countries together.
President Obama has had eight years to create and maintain a successful relationship with Russia and its president. The result has been an apparent loss of Vladimir Putin's respect and adherence, coupled with a few public bouts of irreverence. Putin has shown a contempt for our sitting president and his policies on multiple occasions, both in word and in deed. President Obama's response has been almost submissive. Despite what many may think about Trump, his assertiveness and exceptional business acumen cannot be denied. Hopefully he can bring those qualities to the Russian foreign relations effort when he takes a crack at Putin for himself.
No, the United States should not invite Russia over for tea. While many see the expulsion of Russian diplomats as a pretty mild response to the cyber hacking, it is definitely only the beginning. It was intended to be a small slap on the hand so as not to blow up all relations with Russia or to spark a violent response. There will be more to come.
