I'm trying to figure out how much hassle checking in luggage would add to my route. I was assuming I don't need to pick up luggage and check it back in at WAW, but perhaps I do?
So you are actually going Schengen to Israel, and as for your original question, Israel would never let you board a flight without going through security at ATH...
As
KLouis said, luggage would be checked from NRT to ATH, you would do immigration in WAW, and at ATH you have no option other than to go landside.
The flight to TLV will probably have additional security and 4 hours is still probably OK. If it were another non-Schengen destination 2.5-3 hours might be enough for a self-connection.
