Trump isn't holding the US hostage. He was elected and is still insanely popular.
Trump, as bad as he is, isn't the problem. Trump being president is a consequence and manifestation of the dysfunctional political system and culture in the United States. The problems will not end when Trump's term as president ends.
The United States is not an ally to be depended on. Canada needs to aggressively diversify its relationships and reduce its dependence on trade with the United States, to strengthen itself and improve its resistance and resilience to the ongoing assault and interference.
As the United States continues to decline, its aggressiveness will only increase.
