Thank you, that's my point. If you think Houtis are a proxy, then you think Ukraine is a proxy for the US, as Houtis have to promise concessions to Iran in exchange for armaments. Better yet, they choose their target without iranian input, so they are even less of a proxy than Ukraine who has been forbidden by the US to use the weapons they were given outside of their borders.
If you think Hezbollah are an Iranian proxy, then Israel is an US proxy, and Hamas is a Qatar/Likud proxy (won't be the first time the far right pay agitators to kill their own citizen to stay/be in power, just look at Italy).
