The USA 🇺🇸 has no security pact or treaty with the Ukraine 🇺🇦. Ukraine 🇺🇦 should therefore not expect anything.

The USA 🇺🇸 is well within its rights to halt military arms and capital aid that in its opinion may prolong the war and even escalate it into WWIII unnecessarily.

US defense should be constrained to NATO or those with security pacts and treaties. Support for Ukraine 🇺🇦 that is outside of this criteria is morally questionable and unlikely supported by the USA 🇺🇸 citizens.
