CANDU reactors where in part cheaper than the alternative because it didn't need to enrich uranium for the reactors. AFAIK, Canada does not have the facilities for enrichment.
Definitely not, nuclear weapons are dangerous and should be banned, only the benevolent United States should have them. If you ever find yourself in the position where you are fighting against the United States you need to take a good look in the mirror and turn yourself in at the nearest world police station.
I mean it's just a painful reality that if you don't have a nuke you're at the mercy of stronger Nations. That other nations will with impunity abuse you. No one will protect you. Every country should try to make nukes. That's a fucking terrifying Prospect but it's still true from a geopolitical standpoint.
Yeah, non-proliferation was backed by US security guarantees. Something successive presidents on both sides didn't mess with. Now that we see the Americans are stupid enough to vote in a certified moron, it's best every state gets nukes. I only hope the soft cocks running Australia see that before it's too late.
I don't like the idea of a potentially world ending nuclear stand-off, but we've learned well enough from these past couple of years that having nukes is the only way to guarantee your country's sovereignty against other nuclear powers.
