We said we would aspire to buying US gas. EU can't order member states around like that, and the member states themselves can't order private businesses who to buy from; US can't actually ship much more, even if it could it can't do so to us; and that's about 100% of our imports anyway (not just replacing Russian, replacing all of it) and the way global markets and fungible goods work is that it makes no difference who we buy it from or who sells it to us anyway.
