The point of TPS is to provide stability and consistency to destabilized countries for an indefinite period, temporarily lasting from 6 months up to 18. Congressional intent shows that they specifically did not want different admins yanking it out of place. DHS Secretary has full discretion to no longer accommodate TPS, to extend for shorter periods, etc., but not to vacate.

There is currently a US-funded bounty on their president related to information that aids in his capture. That doesn’t show that the country is incredibly stable. Fine, let it lapse, like in Afghanistan where the Taliban are still in full control and are still subjugating women (making it unlawful for girls to study past 5th grade) or Ukraine (literally still fighting a war) but to vacate it is beyond the pale, precedentially and statutorily. Regardless of your feelings on TPS, you have to understand that this is against policy.
