The Ukraine military was already using starlink. Starlink agreed to provide their service to the Ukraine military as a US military contractor with the US paying the bill.

So they can do that because they have already done that.

The US has committed to defending and replenishing Starlink because they’ve been doing that by protecting the antennas and replacing them as they get attacked.

Again. Starlink already agreed to be used in Ukraine and at the time that Musk interrupted service to the Ukrainian military it had been in use for a long time.

Musk only interrupted service long enough to prevent the counter attack on Russia. Then agreed to turn it back on after the opportunity for a counter attack had passed.

Seems pretty obvious that Musk stepped in to help Russia as a traitor to the US.
