That Corbyn fella...

I imagine that Jeremy Corbyn is likely to share (most of/all of) Bernie Sanders' view:

Putin may be a liar and a demagogue, but it is hypocritical for the United States to insist that we do not accept the principle of “spheres of influence”. For the last 200 years our country has operated under the Monroe Doctrine, embracing the premise that as the dominant power in the western hemisphere, the United States has the right to intervene against any country that might threaten our alleged interests. Under this doctrine we have undermined and overthrown at least a dozen governments. In 1962 we came to the brink of nuclear war with the Soviet Union in response to the placement of Soviet missiles in Cuba, 90 miles from our shore, which the Kennedy administration saw as an unacceptable threat to our national security.

And the Monroe Doctrine is not ancient history. As recently as 2018, Donald Trump’s secretary of state, Rex Tillerson, called the Monroe Doctrine “as relevant today as it was the day it was written”. In 2019, Trump’s former national security adviser, John Bolton, declared “the Monroe Doctrine is alive and well”.

To put it simply, even if Russia was not ruled by a corrupt authoritarian leader like Vladimir Putin, Russia, like the United States, would still have an interest in the security policies of its neighbors. Does anyone really believe that the United States would not have something to say if, for example, Mexico was to form a military alliance with a US adversary?
