Take a look at this article:
Canada Refuses to take part in the US missile defence program
The rational behind the Federal Liberal government’s decision is that they want to be different from the US and be sovereign from the US. They don’t want the weaponization of space and have the US dictate how to handle incoming missiles.
But without taking part in this program, Canada won’t have ANY say on how the US will handle incoming missiles making the US the ultimate country to decide how to handle what happens with MIssiles in Canadian borders. So instead of being a soverign nation, Canada, without input, has given up their defence sovereignty to the United States.
I just don’t understand this government.
