Think back to Pelosi & Harris making public the demand that they wanted the nuke codes.
So you can take from that that they may have been signalling China that they (& Bidan) don't have control of the military. Could mean, too, their inside comms might be gone or under surveillance and they had to find another way to get the message out.
Trap is/was, then, let Bidan play president and draw China out in making their move on Taiwan, thinking Bidan will call the dogs off.
Saw reports somewhere that Taiwan is nuked up against a Chinese advance. Most likely US nukes, if so, under US military control.
Looking more and more to me like Savin is acurrate here, Biden was allowed political control, but not military.
