Israelis haven't strictly "stolen" land in the most technical legal sense, but they've definitely played dirty & did plenty of things that might have been lawful on paper, but would NEVER pass even a casual "smell" test.
Some of Israel's common tactics:
1. Deny building permits to Palestinians. In the entirety of East Jerusalem, something like 2,000 Palestinian building permits were approved over the span of DECADES, while the overwhelming majority were refused (often, for vague reasons, or no stated reason at all), or were never formally refused OR approved & were simply "lost". Eventually, the Palestinians gave up, and built additions/buildings/etc without them. The Israeli authorities eventually catch them, hit them with daily fines, and often go in, demolish it, then tack on an even bigger lien for the demolition costs until the liens. They then find an excuse to take the property by Eminent Domain, and ultimately give the family nothing because the assessed fair market value is less than the liens they've piled on over the years.
2. Make it physically impossible for Palestinians to REACH their property (esp. farmland), then use a law that allows the government to classify those lands as "abandoned" & take them.
3. Some combination of 1 and 2, but squeezing the owners until they're impoverished and either can't afford to pay the property taxes for land they aren't allowed to use, or finally decide they're basically burning good money paying taxes on land they'll never be allowed to use. Tax lien, lien sale, Israeli buyer, done!
Strictly speaking, the actions of the Israelis are "lawful"... but almost nobody would seriously argue that they're "fair". By any objective standard, the deck gets hopelessly stacked against the Palestinians, then the Palestinians get blamed for being taken advantage of. How would most of US react if we owned a farm, the government built a 50 mile wall that put our house on one side & our farmland on the other, then told us we had to a) actively farm the other side to avoid forfeiting the land, b) couldn't get a building permit to build a new house on the other side of the wall, because THAT land was zoned for "agriculture" and not "residential", c) spend 2-4 hours traveling each way to get from one side of the wall to the other, along a route with multiple checkpoints (any of which could refuse permission to pass, for any reason... or no reason at all)? Or if the roof were damaged by a shootout involving the military and a neighbor, then the city refused to issue a building permit to repair that roof damage, then turned around and fined you for repairing it without a permit that you never would have been allowed to get in the first place?
I know a few Israelis. Without exception, they all hate the status quo and feel bad about it... but nobody has any idea how to dig themselves out of the problem in a way that won't ultimately make matters worse. And every time someone towards the middle of Israel's political spectrum comes up with an idea that might partially untangle the mess, the extremists at both ends gang up on them, tear them apart, then resume going after each other.
