On point one. Does the UK have a strategic partnership with the Ukraine?
Yes. "The UK and Ukraine have recently signed the Political, Free Trade and Strategic Partnership Agreement, engaged in a rigorous defence dialogue and forged a cooperation agenda in the defence industry. The UK has stepped up its support to Ukraine to help it resist Russia's hybrid pressures." So that is quite literally true.
Does the US? Yes (I'll just repost:
https://www.state.gov/u-s-ukraine-charter-on-strategic-partnership/). So that is literally true.
Now, you understand that these are legal documents between states, yes? I.e., the difference between media reporting and state diplomacy? So you now surely understand that you are wrong on your first point.
South Korea and Israel are not the models to use here. Each has a direct line of inheritance (into the security framework) from colonial state/war to legal agreement with mutual defense implications. Ukraine is much more similar to Saudi Arabia or Indonesia. There are existing diplomatic relationships which classify (state-to-state) each other as "allies" in areas of military and economic cooperation.
Which terms am I not understanding here? "Alliance"? Because from my perspective I am refuting quite a lot of what you assert as fact with actual factual documentation and you are simply ignoring it time and time again (whereas Raoul, for example, insists upon a different distinction, you insist upon not engaging with facts presented to you).
There is literal proof to the contrary (including documents between each state with names such as "strategic partnership"). It does not have a mutual defense necessity clause, like NATO, but that has been pointed out two pages ago and still this argument continues?
