No, it's not that they're evil.
It's worse, for evil frequently is recognized and fought back yet for decades America has not awakened to what has been going on in the political and media establishment. It was evident during the Vietnam war and has only gotten worse since.
For those who don't recall the Tet Offensive was an attack launched by the NVA and VietCong by some 70,000 troops in a coordinated series of attacks across more than 100 targets. It was an attempt to foment rebellion among the South's population.
Tet failed in its military objective, in that there were too few troops spread too thinly, and once the US and South Vietnamese figured out what was going on they literally slaughtered a huge number of the attackers. To put perspective on this at the Battle of Hue roughly 500 US Marines and South Vietnamese were killed but over 5,000 NVA and VietCong died in that one battle alone.
The story was repeated through the country; while the North managed to attack they lost virtually the entire attacking force, while not managing to take one mile of territory. They also failed to incite rebellion, which was the primary goal of the offensive in the first place.
Our media, however, reported that we lost. They were present and they lied, including Walter Cronkite. Cronkite reported in February of 1968 that the war "was a stalemate and probably unwinnable" despite knowing that the NVA had virtually been rendered soldierless in the Tet offensive as their casualty rate ran ten times the South's.
Tet was a desperation move; the North was in serious trouble. They were failing to take territory and losing men and material at an ridiculous rate compared to the Americans and South. Simply put we were the better fighting force and it wasn't a close call. In the first few days of their "offensive" they lost ten thousand men against about 750 on the other side and it just got worse from there with total losses on their side being close to 50,000, or virtually all of their remaining fighting-age force.
