John Bolton is a war monger for sure. But he is also a realist, which is becoming a dying breed in today's America.
I strongly believe the rot in America started with the Fall of the Soviet Union. All checks and balances and geopolitical considerations were removed then as 'The End of the History' itself arrived in early 90s. There is a rapid decline in American leadership perhaps starting with Bill Clinton '92 and a point has come that an analyst today said that the GW Bush of 2003 look like a statesman compared to Trump. Even Bush Jr! Every American and the world should hope and pray that Trump is really the bottom of the barrel and the barrel doesn't contain rose water, to stay the least.
