After three weeks of airstrikes, Israel has begun its ground invasion of the Gaza Strip. The goal, in the words of the defence minister, Yoav Gallant, is to ‘wipe them [Hamas] off the face of the Earth’. But without a long-term political vision, this objective is unachievable. Even if Israel deals a powerful blow against Hamas, the country risks becoming trapped in a long and costly war that will cause a dangerous blowback across the Middle East.
