Assuming todays NATO is supposed to be a counter balance to Russia
then NATO is useless without the USA.
Of the 28 countries that are members the US is the only one capable of
deterring Russia. In fact take the US out of the equation and Russia could
concur Europe in a couple of months.
Just take a look at the death and destruction a bunch of rag tag jihadists
have inflicted across Europe and then think of the military might of Russia.
They better pray to their deities that we never abandon them.
