Even if they are, so what?
If you were looking at a different country that was actively being bullied, would you argue some crap about centralizing power?
If Denmark started centralizing power in response to trumps threats to the sovereignty of greenland, then what?
You talk like this is a problem that government is responding to external existential threats in the means that are available to them.
Are you arguing the Carney government should relinquish power?
Should they decentralize their capacity to influence things inside the country?
Perhaps you can answer just this.
What is your point?
