'People fight back': Military expert warns Trump vow could trigger decades-long insurgency

President Donald Trump has repeatedly mused about making Canada into America's "51st state," which has prompted one expert to conduct a war game mapping how a U.S. invasion of Canada would play out.

The Montreal Gazette reported that Aisha Ahmad, a political scientist at the University of Toronto, said that the American military would likely easily defeat Canada were Trump to really give the green light for an invasion.

However, he also said that wouldn't be the end of the story as Canadians would not passively accept being conquered.

In fact, Ahmad believes that Canadians would wage a bloody, decades-long insurgency against the United States until the Americans left their country.

“It’s impossible to annex Canada without violence,” said Ahmad, who in the past has advised American officials at the United States Department of Defense about counter-insurgency strategies. “No one is born an insurgent or resistance fighter. This is something that happens to people when their mom is killed, or when their kids are unable to get to a hospital. People fight back because they have to.”

He said that the U.S. military would struggle to occupy Canada when hundreds of thousands of Canadians would be engaged in a concerted campaign of sabotage that they would adopt as a "secret, part-time job."

"Trump is delusional if he believes that 40 million Canadians will passively accept conquest," he emphasized.

In fact, it would only take one percent of the Canadian population working as insurgents to produce a force of 400,000 fighters, which would be ten times the number of Taliban fighters who eventually pushed the American military out of Afghanistan after a 20-year occupation.
