Its true:
Canadian Intelligence (CSIS) Director Jim Judd testified recently before the Senate committee reviewing Canada's anti-terrorism legislation, he noted there were now suspected terrorists in Canada that "have had no discernible previous link of any kind with the terrorist networks." Canadian intelligence experts believe that converts to Islam in the country are becoming a major source of Al-Qaeda combatants and pose a risk to security.
An intelligence report from Canada's spy service, released to a daily said "there is a direct threat to Canada and Canadian interests from Al-Qaeda and related groups," and that those groups are attempting to expand their support in Canada. "Converts are highly prized by terrorist groups for their familiarity with the West and relative ease at moving through Western society," the recently declassified Canadian Security Intelligence Service report said.
This is from a few years back but nothing has changed. We need to look after both borders. When either we or Israel go after Iran you can expect an attack from their Hezbollah or Hamas proxies living on the government dime in Canada. According to the RCMP, over 50 known terrorist organizations, comprising more than 10,000 individuals, operate in Canada. I think the new SEC/DHS must have just got the briefing.
I don’t disagree with your examples, just don’t ignore the multitude of evidence that terrorists cross the Mexican border as well.
You missed the point of the conversation:
““The danger from the South is mexicans.
The danger from the North is muzziecans.”
The point is, it’s not ONLY Mexicans coming across the southern border.
