Backdrop for Putin summit: A pattern of Trump disrespecting allies?

President Trump has wanted to hold a summit with Russian President Vladimir Putin for a long time, essentially from Day 1 of his tenure.

But from Mr. Trump’s perspective, the fact that the long-awaited one-on-one with the Russian leader has now been set to take place just days after a NATO summit he’ll attend with European leaders might seem like a case of good things coming to those who wait.

The president seemed to relish his recent one-two punch of a contentious meeting with America’s chief economic partners at the G7 summit in Quebec, Canada, followed immediately by the historic and ebullient one-on-one in Singapore with North Korea’s Kim Jong-un. So for Trump, the prospect of repeating the formula barely a month later is likely tremendously appealing.
