the precondition for the invasion of syria was taking the air defences
out from the ground, and we see how hard that's been. short of breaking
the russian-iranian alliance, which appears to be strengthening, it's
hard to see how an invasion of iran is even a viable option. i don't
think it's truly on the table; the strategy is cold war, by necessity,
for the foreseeable future. i suspect trump would rather pick on a
country like nicaragua and tie it to immigration.
