War-mongering idiots.
As yankees have always been. Solve any issue with violence. Yell and cry when an American dies. No problem killing thousands or even millions of foreigners.
You are scared of Russia ?
https://en.wikipedia.org/wiki/List_of_countries_by_military_expenditures
US - 610 billion USD
China - 228 billion USD
Saudi-Arabia - 69 billion USD
Russia - 66 billion USD
You are spending 10x as much money on your military than Russia. In fact, the US alone count for more than 1/3rd of the world's military budget (610 our of 1740 billion USD). What are you afraid of ? And what did you get for all that money ? 1 Million deaths in Iraq, and you lost that war. 600k People dead in Syria (started by your buddies from Saudi-Arabia, and backed by you. (And the EU. I'm sorry for that). Syria and Libya in shambles. Afghanistan is still a mess, you lost that one too.
You want to fight the real enemy ? Fight your Republican politicians. Maybe your Trump-voters too. They are the real danger to your country. Fight half your multi-nationals, who bring little value to your average citizen, and try to suck them dry. Fight the 1% and the unfair impact that they have on US politics. Fight Fox News and the alt-right media, who spread lies and hate and really really do irrepairable damage to your democracy.
The Russians aren't gonna do much harm to you. If you start a war with them, you've got nothing to gain. But then again, a few million dead people around the globe don't matter you. Because: why not ?
