I would declare independence from NATO/Five Eyes, ally with China, remove US military bases from my country and then immediately change the date of Australia Day to 9/11 as a joke
I would then start de-desertification and other environmental projects, and start improving infrastructure too.
Atm, since COVID is the biggest issue here in the US - idk fuck it, I’d call all the troops home and use them to quarantine/declare martial law/distribute food, water, masks, vaccines, etc. in regions where the virus is exploding and/or local officials are unwilling to comply with federally mandated mask requirements and lockdowns.
Following that, with huge portions of the population off the streets we sort out (mostly in this order) universal healthcare, publicly owned infrastructure projects (trains), and free housing and education. Somewhere in there we start developing a green energy grid in earnest and do anything else important that I forgot. Oh yeah and no rent and everyone gets a check every month for however long this shit lasts.
Bing bang boom we re-enter a much less shit country than the one we had pre pandemic. Way long term we should work to call a second constitutional convention or something. The senate and Supreme Court have got to go at minimum.
