You mean the wall that had multiple useless sections built with American taxpayers money and he absolutely would have continued with if not for the inherent logistics issues of physical reality and lack of competent enablers that aren’t blockers this time around?
Also, the 2016 administrator WAS catastrophic. The hyper consolidation of corporate actors, deregulation and defanging of admin agencies that effectively removed all culpability from corporate actors, and bureaucratic damage that has made recovery a steeple uphill battle all happened not just under his watching but as an explicit intent of his watch.
I think his intentions are very clear and he very often speaks them. Where Trump is utterly full of shit is where he describes reality, as in migrant crime waves, how tariffs actually work, Haitian pet eating, etc. And most of it he couldn’t get before because there were process barriers in play. Much of that has been cleared both in the intervening years and as a direct result of the down ballot of this election.
