We too wonder why we give so much aid to other people instead of our own. We too ask why Trudeau is so intent on pandering to everyone, and the answer isn't a surprise.
Trudeau needs to maintain Canada's reputation due to immigration and tourism.
Canada's selling point and strong suit is its diplomatic status as the friendliest nation on Earth. People are more likely to trust us and broker deals with us.
Why Trudeau takes this so far is beyond my ability to comprehend as well. But rest assured in knowing that you are right.
Trudeau or the Canadian Government doesn't care about you or any other country. They are serving their own interests first, that of Canada. Everybody is self serving.
Welcome to real life.
