The real question might be whether the compiler was smart enough to change var++ and var-- into ++var and --var when the initial values aren't needed.
As compiler optimisations go, it's a fairly obvious one, but it was 1974 and putting checks like that in the compiler would increase its size and slow it down when both space and time were at a premium.
On the one hand, Hungary has remained somewhat different from its neighbours because it's surrounded by mountains and hard to get in or out of by land so it would seem a safe bet for a swap, but on the other, it's the 21st century and mountains aren't so much of an obstacle any more. Would we really want to give Putin an airstrip in the middle of Europe?
It would be foolish to assume Putin's expansionist plans are limited to Ukraine. It's just that Ukraine is proving a bit more difficult than he expected and he's had to concentrate his efforts there.
