...and Congress was your little beeyotch, what would you do? The South Africa thread got me started thinking. This is all far from complete, and definitely not well thought out... I'm just babbling.
#1 Do what was needed to permanently re-establish a harsh and stringent interpretation of the Bill of Rights (It means what it says).
#2 Develop safer oil resources outside the Middle East in preparation for hard times.
#3, I would cut all funding to both Israel and the Arab nations, expecting chaos and oil shortages. War would be a foregone conclusion, so we'd need to be ready to do without. OTOH, we could finally wash our hands of the whole region.
#4 Offer citizenship and land to both any Israelis and any Afrikaners or Rhodesians that wanted, and help evac them quickly... especially getting any Israelis that wanted out before the Arabs went nuts. I've known several of each, and they have what it takes to be better Americans than most Americans do. I'd turn over the dry wastes out west to them, selling it cheap and fast tracking citizenship. They'd turn them into green paradises in 10 years.
#5 Seal the borders with our troops, and deport anyone that didn't have their proper permission to live and work here. Then, I'd make it simple to apply for and get legal status for people with something to add, so that they could work here and pay taxes... and if they want to live here permanently, get them into the system as citizens.
