Deborah Orr: There wouldn't have been Gaza rockets without the blockade

Supporters of Israel's action are fond of reiterating Israel's narrow justification for its action. Who else would put up with regular rocket attacks from a neighbour, it asks? No one suggests that they would be happy to. It is accepted that Israel has the right to defend itself, and so it should be. Yet few would acquiesce without protest to a swingeing two-year blockade by a neighbour either, though no Western leader ever seems seriously to ask that highly pertinent question.
