Canada, Mexico, the UK, the EU.
I can guarantee Africa, South America, Australia, New Zealand... All countries are paying attention.
All are recognising the US as significany weaker than they have been in a long time. All of them are making power grabs by supporting Ukraine and investigating new trade alliances/deals not involving the US, further weakening US power.
While these are absolutely the moral and correct things to do, and supporting Ukraine is the human thing to do, bolstering international security - there is also a huge amount of soft power to be had in the support, and a good reason to up domestic arms production which helps replace/offset Americas hard power (IE military might).
Where countries have relied on American weapons before, the threat of America "switching off" a countries jets and missiles cannot be ignored.
