Has the meeting in Helsinki reset US-Russia relations?

It seems few share US President Donald Trump's optimism that his summit on Monday with his Russian counterpart Vladimir Putin in Helsinki helped dispel some of the tensions between the two countries.

True, just as Trump said before the summit, the world wants to see him and Putin get along, since they are the leaders of the world's two most heavily-armed nuclear powers and relations between the two countries continue to deteriorate.

However, their longtime enmity, which can be traced back to the Cold War era, and their opposite positions on some critical international issues and their power wrestling in Syria and Crimea, indicate the contention between the two big countries will not vanish any time soon.
