Letting the US dominate the world is not the perfect thing, but it's 100 times better than letting 中共 or Russia dominate the world. This is exactly the reason why the rest of world give the US the right to print money, because they understand maintaining the current world order requires money and are willing to pay for it
Some countries may raise some concern and ask US to have some restraint. But no country plans to do anything about it because they understand the responsibility the US has to shoulder in the dangerous world who are living in. Canada will not be able to defend itself without having such a powerful and friendly neighbor in the South.
