Does collateral damage in war have a limit – can you destroy a missile base that will kill many civilians in the town nearby. Can you hit a nuclear reactor that will contaminate millions?
Are citizens who support the regime considered combatants?
What Issurim can you be Doche because of mental health – using phones on Shabbos, or other electric devices that will calm them down?
Does Iran have a Din of an active Rodef if it’s only something in the future – they’re in middle of making a nuclear bomb that won’t be ready for another two years?
Is it a Milchemes Mitzvah to start it on Shabbos ?
Can you be Mechalel Shabbos for preventive action – such as attacking on Shabbos to preempt an act (Is it תלוי בהותרה או דחויה- smoking while driving a tank)?
Do you have to go to a shelter (odds of getting hurt are very small)?
Is a tank Chayuv in Mezuza? Can you make it into a Sukkah? Light Chanukah Neiros?
Can you listen do the Megillah on zoom?
And more….
