NATO would lose against Russia in the outbreak of World War 3 and Donald Trump’s recent actions at the summit has reduced the alliance’s strength even further, according to a leading think tank.
Nato was formed in 1949 in response to the threat of the Soviet Union.
The USSR responded with the Warsaw Pact, which was a collective defence treaty among the Soviet's satellite states.
Trump claims Nato members are not spending enough defence
Although the Soviet Union collapsed in the early 1990s, Nato remained in place.
Tensions have recently resurged between Russia and the West and some have even dubbed it a "New Cold War".
Since the 2014 Russian military intervention of Ukraine, Nato has moved to bolster its eastern flank by creating the four battlegroups at a 2016 summit in Warsaw.

Nato may have four and a half times the number of aircraft if compared with Russia and the only fifth-generation warplanes on the battlefield, but according to a 2016 report by Rand Corp: “The Russians have advantages over current NATO forces in integrated air defence, long-range artillery, anti-armour munitions, and electronic warfare.”
A report from May 2018 said: "Given NATO’s current posture and capability, including the European EFP (Enhanced Forward Presence) battalions and rotational US armoured brigade combat team, Russia still enjoys a substantial time-distance advantage in the initial days and weeks of a conventional ground campaign against the Baltic States.
"Looking out past the initial weeks, the comparison on the ground would actually get worse for NATO before getting better."
