I think that's never a good excuse.

Arab states use Israel's existence as justification to military dictatorship. Saddam also used the threats from Iran (which were very real).

Meanwhile, Israel managed to develop into an industrial democracy despite being surrounded by enemies from all directions.

Israel treats it's Palestinian population as if it were a military dictatorship.

Yes, that is occupied enemy territory, not the nation they purportedly serve.

Treating occupied enemy territory the way that Israel has treated Palestine violates international law in so many ways it's frankly ridiculous. They really are acting like a military dictatorship.

Was South Africa really a democracy under apartheid? Or the US under Jim Crow? Or Turkey currently?

I don't think you can be considered a democracy if you are at war with half of the people within your borders.

Democracies are always local.

Was the US a liberal democracy during WWII when it cluster bombed Germany and Japan?

Think about the context here: how South Korea in the 80s was treating its own people.

Israel is a democracy within its local population despite being surrounded by enemies.

Therefore, having an enemy at the border is not a good excuse for a military dictatorship.

I haven't been to Gaza, but I grew up in South Korea in the 80s. If half of what I see in the news is true, how Israel treats people of Gaza is much worse than how South Korea treated people of Seoul in 80s.

Put another way, I'm sure even Pyongyang has some happy citizens. Even dictators usually let some local population live happily. The trick is being part of the right local population.

Gaza is practically enemy territory for Israel ..

Containment as a foreign policy led to extremely bad outcomes globally, as did colonialism. It wasn't just SK treating it's citizens poorly, it was the vast majority of second and third world countries that had a history of colonial subjugation. Looked through the lens of colonialism, it makes perfect sense.

Of course not.
