I wonder if the ongoing siege of Gaza counts? Counting 15 years. Or does it not count without any active fight back OR because Gaza is a part of Israel and thus Israel has laid a siege on itself?

Not a siege in any sense. What sieges not only allow the besieged to conduct import/export but actively pay for the besieged’s supplies?

Leave the ideology somewhere else

Which ideology are you referring to here? I don’t see one in their comment.

It's a thinly veiled "every criticism of Israel is antisemitism".

Does it matter if some supplies are let through if the end result of attrition is still achieved?

Thanks for the correction. It looks like it was the longest siege ever against the British. Certainly a massive qualifier there I forgot.
