Jokes aside, our model of government doesn’t really require the prime minister to function, or even cabinet ministers.
If the US really wanted to bone us from a government perspective, kidnapping King Charles and the current Governor General would actually be the most significant.
We would be unable to pass laws at that point until a new British monarch could be installed and appoint a new GG.
Money spent on soldiers, bases, equipment, etc. would be absolutely useless when the US Military simply double tap every single military base in the country in the first 10 minutes. There are only 27 across Canada. Even if we added 100 new bases to spread things out they could easily do the same thing still. We are far too close, and the military capability difference is absurdly ridiculous.
The two possible things I could think of that would realistically make the US think twice, a) handing out guns and training to civilians en masse and b) a PR campaign to the US population (and military) that may lead to a refusal to invade by the troops.
I’m pretty sure A isn’t going to happen.
No amount of realistic military spending by Canada would help this situation.
You can absolutely use your external IP rather than a domain, your ISP likely keeps your IP the same for long stretches of time. Mine only ever really changes during long power outages.
You can get around that the IP issue by broadcasting your ip from your local machine to a known service, there are some free ones but they aren’t the most stable things in the world if it’s critical. Google Dynamic DNS
It might take the world… Going to war.
It would be kinda funny though if he kidnapped Carney, we kept everything going without him anyways, and then we sent a sleeper crowd to storm and burn down the Whitehouse again.
