When the effort is no longer profitable...
Most of the powers in DC have bought into the lies of Malthus and of overpopulation of the planet, along with the climate catastrophic BS, and want to 'pare down' how many people are in the world, including in the US.what
They've been at it for decades, starting back with forced sterilizations of Native Americans even into the 60s, and with their policies of trying to destroy the family unit with stuff like no fault divorce and praising single motherhood.
It's also why they praise the troon shit, as it's people sterilizing themselves while being told they are brave and yet oppressed.
The powers in DC want there to be less humans period, including their voters, and the DoD still hasn't caught the fucking memo because it's trying very hard not to notice things like that about it's chain of command.
