It's looking like this may have been a waste of time
Donald Trump does not like to have his time wasted, and he certainly does not like being played.
Unless some kind of concession was mad on Putin's side behind closed doors we're not aware of, expect Trump to ramp up economic and political pressure on Russia significantly.
Trump wants this war over. He wants his legacy to be bringing peace to Europe. If carrots don't work, and this summit was about as big of a carrot as one leader can give another, then expect to see the stick soon.
