Again poland could if spotting a foreign drone within polish borders would have to surveil it and decide if its an actual viable threat, and then shoot it down. if not a threat or in international space or other things then poland can just watch and report and gather more evidence to strengthen viability for future incursions to be probable threats
Yes that is correct. They will assess the threat and based on previous experiences,

Regarding Israel, I agree that they cannot legally attack a foreign country without a declaration of war.
The real solutions are the agreements for disarmament from all sides, but that is currently impossible.
declarations of war are towards the country(government, military, citizens as intended targets) that the strike happened in. however there are other laws that allow "pre-emptive strikes"
"military actions" and such, to take out specific intended targets that are not part of the wider host nation.. without it leading or needing a declaration of war, if such strike
ashas significant military defence strategy and mitigating risk/loss of the host country housing the military threat that was
targeted.a intended target different to the host nation, it can be deemed as a pre-emptive strike
/"military action" and not lead to war. especially
(emphasis) when the intended targets of the strike were not that of citizens nor military nor government
of the host country the targets hide in
