Dude, tell me, who represent the United Kingdom?
Is it the head of state Queen Elizabeth? Or is it the Prime Minister Boris Johnson?
President is THE HEAD OF STATE of the United State, the congress and the senate to be precise is the people who was chosen to represent America.
And yes, if Biden does not have both congress and senate backing, what he said is what he said on G7, it does not mean this is what we do. Do you even remember Biden said on Saturday that Putin "Should not be in power" does that mean the US as a whole support a regime change on Russia?? Or even does it represent the United States when he said that??
Man, you are dumb. Report me if you want, but I got no other word for you.
If case you are still too stupid to catch up, Boris Johnson represent the UK because he IS the leader of the conservative party in the UK, which is the leading party in the government. President Biden is just a President, he have no control of either Congress or Senate. The most he can do is to issue executive order, which other than banning people like you to enter the US, he have no hold in any foreign or domestic policy in the US. Saying otherwise is just showing how you do not understand US politics.
