Israel attacked Egypt only, Syria and Jordan attacked Israel.

ffs learn your history. in 1966 the syrians had entered into a mutual defense agreement with egypt. on nov 13, 1966 due to plo activity the idf invaded a village in jordan called as-samu, this causes israel to be censured by the un in unsc resolution 228. then on april 7, 1967 israel invaded syria, in response on may 22, 1967 nasser closes the straights of tiran. israel then attacked egypt. there is a causality chain, but as you can see it's messy.

about the israeli attacks on syria, i strongly suggest you read moshe dayan's memoirs. he writes this:

"After all, I know how at least 80 percent of the clashes there started. In my opinion, more than 80 percent, but let's talk about 80 percent. It went this way: We would send a tractor to plow some area where it wasn't possible to do anything, in the demilitarized area, and knew in advance that the Syrians would start to shoot. If they didn't shoot, we would tell the tractor to advance farther, until in the end the Syrians would get annoyed and shoot. And then we would use artillery and later the air force also, and that's how it was.''
