Canada

It would be colossally stupid to put out a press release that tells the other players what cards you’re holding

There are public commitments that indicate betrayal of Canadians, though:

• Defense pact with Philippines is direct support for US war on China.
• G7 statement on "Iran must not have nuclear weapons", while a platitude, is direct support for all Israel hasbara (weeks/months away since 1980s) and war on Iran. By extention, support for US and their strikes.
• Ukraine aid is simple continuation of US proxy war on Russia, even as US "forces" colonies to pay for it, including most recent proposal of NATO buying US patriot missiles to gift to Ukraine. Dividing EU from Russia is US policy. Gaslighting people that US is a better ally than Russia is US domination of NATO.
• Fortress Can Am and banning Chinese investment is further tying/subjugating Ontario/Canada to US without alternatives, and resulting in punishments instead of enthusiasm for the subservience.

When Trump negotiates publicly with lies and public punishment based on those lies, the private negotiations seem not just pointless, as something Trump won't listen/abide with, but more than likely a US trick to pacify us, while we get destroyed with full complicity.

Never interrupt your enemy when they are making a mistake.

• Sun Tzu

Those people also don't appreciate that in the context of Trumps unpredictability no publicly made plans would remain unchanged.
