“President Vladimir V. Putin is in his fifth year of trying to bomb a smaller country into submission. President Trump tried to pull the plug after six weeks, only to be drawn back in,” the New York Times reports.“Neither man has come close to achieving his goals. But the contrast between the relentless killing by Mr. Putin’s Russia in Ukraine and Mr. Trump’s on-and-off bombing in Iran is the story of two leaders of major powers struggling to find their ways out of wars of choice.”“Mr. Putin’s ground invasion of a neighboring democracy and Mr. Trump’s air war on a Middle East theocracy are difficult to compare, and each leader appears convinced that his war is just while the other’s is wrong. But the two conflicts intersect in numerous ways in global geopolitics, from energy markets and air-defense supplies to the diplomatic bandwidth of White House envoys.”
