Are you expert enough to comment on externally driven fusion rockets like Longshot? E.g. instead of trying to contain and extract power from fusion, simply using e.g. fission power to initiate fusion pulses that squirt out the way plasma wants to? I'd guess worst case it converts fission power to high impulse exhaust, best case you have net fusion energy dominating the exhaust and it's easy because you're not fighting the plasma. Mostly I'm wondering if it's as handwavy as everything else or if it's something we'd have a good chance of building if we wanted to.
