As Trump has pointed out, NATO has had the US covering most of the costs and most of the manpower requirements for decades.

If NATO isn't willing to increase their 'skin in the game', then let Russia go where they want to go and take what land they want until NATO members are willing to do so.

Likewise, the last 50 years of trying to 'democratize' the Middle East while supporting dictators like the Shah of Iran and Saddam Hussein and then all the 'regime changes' implemented by Clinton, Bush, Bush and Obama/Clinton, H. have also been a failure.  The leadership there does not want democracy; they want their version of a theocracy, either Sunni or Shi'a or just plain power over the oil if they are secular Kurds etc.

We were only there for oil and ego; we have our own oil, let the egoists send their own sons and daughters over there ala the Spanish Civil War  if it is really that important.
