"67. Merchant vessels flying the flag of neutral States may not be attacked unless they:
(a) are believed on reasonable grounds to be carrying contraband or breaching a blockade, and after prior warning they intentionally and clearly refuse to stop, or intentionally and clearly resist visit, search or capture…
"98. Merchant vessels believed on reasonable grounds to be breaching a blockade may be captured. Merchant vessels which, after prior warning, clearly resist capture may be attacked."
1. There is no "blockade" under international law
Israel's economic isolation of Gaza is not a proper "blockade" under international law. The standard definition of "blockade" is "an act of war by which a belligerent prevents access to or departure from a defined part of the enemy’s coasts." Gaza is a totally dependent, and sometimes occupied, territory subject to Israel's military and economic domination. It is not a "belligerent" or "enemy" state engaged in hostilities with another state. Neither Turkey nor Greece, who share Cyprus (from whose waters the fleet sailed), is in an armed conflict with Israel. An embargo can be properly directed at hostile state actors, not dependent civilian populations like the Gazans.
2. The "blockade" itself was illegal at its inception under these provisions of the San Remo Manual:
"102. The declaration or establishment of a blockade is prohibited if:
(a) it has the sole purpose of starving the civilian population or denying it other objects essential for its survival; or
(b) the damage to the civilian population is, or may be expected to be, excessive in relation to the concrete and direct military advantage anticipated from the blockade..."
"Among the equipment that the IDF agreed to show reporters were medical supplies, including [500] electric vehicles [wheelchairs] for handicapped people, wheelchairs, stretchers, hospital beds and boxes of medicine. They also showed crates full of dry food products and children’s toys.According to [Colonel] Levi, the soldiers also found construction equipment, including sacks of concrete and metal rods. He said that Israel did not allow those products to enter into the Gaza strip for fear that they would be used to construct fortifications for terrorists and for weapons manufacture." [My emphasis and additions.]
The violent seizure of the vessels, which contained no arms or other military equipment, was clearly "excessive in relation to the concrete and direct military advantage" under the section of the San Remo Manual cited above. In fact, Israel derived no "military advantage" whatsoever from its assault on the flotilla in international waters.
“...sage, cardamom, cumin, coriander, ginger, jam, halva, vinegar, nutmeg, chocolate, fruit preserves, seeds and nuts, biscuits and sweets, potato chips, gas for soft drinks, dried fruit, fresh meat, plaster, tar, wood for construction, cement, iron, glucose, industrial salt, plastic/glass/metal containers, industrial margarine, tarpaulin, sheets for huts, fabric (for clothing), flavor and smell enhancers, fishing rods, various fishing nets, buoys, ropes for fishing, nylon nets for greenhouses, hatcheries and spare parts for hatcheries, spare parts for tractors, dairies for cowsheds, irrigation pipe systems, ropes to tie greenhouses planters for saplings, heaters for chicken farms, musical instruments, size A4 paper, writing implements, notebooks, newspapers, toys, razors, sewing machines and spare parts, heaters, horses, donkeys, goats, cattle, and chicks.”
"...Israel permits Gaza residents to receive small packets of margarine, considered a consumption item. Israel bans, however, the transfer of large buckets of margarine, because the buckets are designed for industrial use, rather than home consumption, meaning that they could be used to allow a local factory to produce biscuits." Similarly, requests to permit empty cans intended for the preservation and marketing of Gaza-produced tomato paste have been refused, but requests to transfer prepared, Israeli-made tomato paste are permitted."As long as direct U.S. military aid to Israel continues at its present level of $2.4 billion per year, Israel can just hunker down and continue to act with impunity despite international condemnation for its acts. The high level of support places the U.S. in unique position to influence the Netanyahu government to open serious negotiations with Palestianians toward an overall settlement of this endless conflict. If that's the real goal of the aid missions to Gaza, as Israel claims, then the world has to hope they succeed.
