Why the horrible Israelis inspect Gaza-bound sugar

From Israel Insider:

The defense establishment decided that Israel will continue to supply products that are essential to prevent hunger, but "luxury" items will not be allowed.

"Oil, they'll get from us. Balsamic vinegar - no," Haaretz quoted a security source as saying.

Since Israel changed Gaza's status, it has blocked the shipment of certain merchandise into the Strip, including cigarettes, electric appliances, furniture, and toys. After Gaza-based terrorist groups tried to hide potassium for use in explosives in sacks of sugar, Israeli authorities also started inspecting sugar being brought to Gaza.

Do you think that the pro-terror crowd will mention that when they whine about Israeli restrictions on goods to Gaza?
