First, are we sure it was Russia? There have been many downed Russian drones in Ukraine
,. With a little adaptation, Ukraine could be the one who resurrected and then sent these drones into Poland, afterward blaming Russia.
There are only two things that keep any country or anybody from doing whatever they want:
1. Lack of strength to do it;
2. Their honoring of their agreements - written or unwritten - with others to NOT do it.
Depending on who they have agreements with, and the details of the agreements, this could take some time to determine. They need to hash over the wording and the intent (spirit) of the agreements.
If it was indeed Russia that sent the drones on purpose... Russia doesn't do this without provocation. Since Poland seems to be sending troops
intoto fight in Ukraine against Russia, Poland has set itself up to be an enemy of Russia. If Poland hasn't done this directly, they need to monitor their borders better, to keep Polish mercenaries from going into Ukraine, at least through the Polish-Ukraine borders.
