Reversal of the exchange rates

The exchange rate between Canadian dollar and the U.S. dollar has finally reversed; Canadian dollar is now more expensive than the U.S. dollar. I know that the exchange rate depends on the law of supply and demand and a lot of factors affect it; it's too complicated for me to understand, but as for me, I simply feel that the higher the currency, the stronger and richer the country. The U.S. dollar is getting lower and lower because of the war while Canadian dollar is increasing its value. Euro is keeping its value high while Japanese Yen is unreasonably low affected by the cheap U.S. dollar. European countries are like matured people who are older but wiser. Young American have more energy but they are wasting most of them for stupid wars while Canadian, who is a little bit wiser than his neighbor, is growing into the adult group of European countries. How about Japanese? Well, he is getting weaker as the follower of American. You might think this is a stupid idea full of bias, but I think that the international relationship is just the same as the human relationship in a small school class.
