The answer to the question in the title of this article is that Russiagate was created by CIA director John Brennan.The CIA started what is called Russiagate in order to prevent Trump from being able to normalize relations with Russia. The CIA and the military/security complex need an enemy in order to justify their huge budgets and unaccountable power. Russia has been assigned that role. The Democrats joined in as a way of attacking Trump. They hoped to have him tarnished as cooperating with Russia to steal the presidential election from Hillary and to have him impeached.

Public Russia bashing pre-dates Trump. It has been going on privately in neoconservative circles for years but appeared publicly during the Obama regime when Russia blocked Washington’s plans to invade Syria and to bomb Iran.

Russia bashing is much larger than merely Russiagate. The danger lies in Washington convincing Russia that Washington is planning a surprise attack on Russia. With US and NATO bases on Russia’s borders, efforts to arm Ukraine and to include Ukraine and Georgia in NATO provide more evidence that Washington is surrounding Russia for attack. There is nothing more reckless and irresponsible than convincing a nuclear power that you are going to attack.
Washington is fully aware that there was no Russian interference in the presidential election or in the state elections. The military/security complex, the neoconservatives, and the Democratic Party are merely using the accusations to serve their own agendas.
These selfish agendas are a dire threat to life on earth.
