People are aware of the wars the US wages against other countries. The list is endless. Since 9/11 — a false-flag operation to justify wars of aggression — the US has murdered millions of people. Countless others have been maimed. The US also maintains more than 800 military bases worldwide, one-third of which are in the Muslim East.
There is another type of war the US wages against ordinary Muslims, and some non-Muslims. These people live in Western countries, thus the US cannot bomb them directly. So, it uses other tactics. The US maintains millions of people on its no-fly list; many more are on its watch list.
People on the no-fly list are prohibited from flying to the US or even boarding a flight that goes over US territory. People on the watch list, while prohibited from entering the US, are required to obtain permission from the Department of Homeland Security (DHS) before getting a boarding card to fly anywhere. To their lasting shame, many Western countries have succumbed to US bullying and accepted violations of the fundamental rights of their citizens who have committed no crime. Canada also falls under this category.
Once on the list, it is impossible to get off it. People have had to face long delays at airports waiting to get clearance for a boarding card to travel. There have been instances of people missing their flight because of DHS delays in giving timely clearance. Is America afraid, or does it simply want to terrorize these people?
