President Donald Trump has long bet that he can scare allies into submission. It's a gamble that is increasingly being tested ahead of the Group of Seven summit beginning Monday in Canada.

Global trade will be a major focus at next week’s G7 summit as world leaders gather in Alberta, including U.S. President Donald Trump, who will be making his first appearance at a major international event since returning to the White House in January.

Protests during the upcoming G7 leaders summit in Kananaskis, Alta., may be starkly different than demonstrations happening this week against immigration crackdowns in the United States.
