Just because a thug makes a valid point doesn't make him any less of a thug.
Vladimir Putin is not our friend. Putin is an ex-KGB autocrat who steals territory from his neighbors, imprisons and assassinates his opponents, and stages photographs of himself to distract the world from the fact he runs a rusted kleptocracy wholly dependent on fossil fuels. It's all very Clintonian.
More than anything, Putin is a predator. What all predators have in common is that they are skilled at recognizing and exploiting weakness. Note the fruits of Obama's "Russian Reset," one of the cornerstones of his foreign policy agenda. Obama thought that by playing nice with Putin, the Russian autocrat would behave himself and pursue policies of mutual benefit. What happened, predictably, was that Putin correctly read Obama as a chump, and he deftly exploited the full measure of the mauevering space that the naive US administration ceded to him: he plunged Ukraine into a permanent state of civil war, stole Crimea, strengthened his relationship with Iran, outflanked him on Syrian chemical disarmament amidst the "red line" fiasco, and has now extended Russian military lethality into the heart of the Arab world.
Such is what we sow when we misread international predators. I would hate to see President Trump make the same mistake. Putin is not our friend- he is an antidemocratic strongman in the mold of generations of Old World autocrats. The fact that happens to also be of an anti-globalist persuasion does not make him our friend.
