I see you are forgetting the Republican playbook from the Cold War. The US crashed the Soviet economy by telling its client state Saudi Arabia to overproduce oil and tank the price of oil in concert with the US and its allies.
The problem Biden has is that his predecessor fucked up and pissed off the Saudis into the Chinese and Russian sphere. You don't get to blame the man whose having to deal with a problem another man caused. That's called being blind and leads to the bullshit of Chinese, Russian and Belarusian governments.
Starlink isn't free the Ukrainian government has or I should say had an agreement to pay Musk back after the war. With that idiot now seemingly kissing Putin's arse. Deactivating Starlink in areas Putin just declared Russian but which are under Ukraine's control I don't think Ukraine will follow through with that promise.
I hope Musk gets his arse handed to him that Commie Loving bastard.
On more on topic news. Russian and Collaborator administrators have all fled overnight from Kherson. They left with no warning abandoning their belongings except for cash and other mobile assets. Several were recorded by several cell phones driving off at high speed in the wee hours of the night. Furthermore this morning Russian diplomats tried to propose a ceasefire with Ukraine and offered to surrender Kherson in exchange. The Ukrainians told them to "Fuck Off! Were taking back everything!"
