Despite Trump's signalling of approval for using U.S. weapons in Ukrainian strikes on Russian territory, the reality is that his administration has quietly blocked Ukraine from taking such action as he believes this would scuttle hopes of making progress with Russia in negotiations.

This talk of U.S. approval for Ukrainian strikes on Russian territory is irrelevant as Ukraine has been domestically producing a number of weapons for some time now, meaning that should Ukraine wish to launch retaliatory strikes on Russia, it does not need to ask anyone's permission.
