So if Russia had better equipment, training, army etc, on par with the US for example, so there was no realistic way they would ever get it back, or if other countries weren't giving as much aid, then they should just accept the "two state solution"? Do you really think that?

In Israel, there is NO realistic path towards them EVER getting territory back from Israel.

Also I don't really agree with this framing. Perhaps it's not likely but Israel could acknowledge that people have been removed from their homes and allow Palestinians back into their towns with equal rights. Super easily. They could remove illegal settlements. Etc etc etc. These things are choices that it is totally possible for any compassionate human in a position of power to make.

I agree that this is not going to happen (lacking a compassionate human with sufficient power, maybe) but let's not pretend such a thing is impossible.
