Benjamin Netanyahu spent years converting Israel's bipartisan US relationship into a personal asset, binding it to Trump's Republicans. The Democratic sweep of Congress has turned that asset into a live grenade. The opposition now frames his leadership not as diplomatically aggressive but as structurally dangerous — the man who lost America. The numbers tell a clear story about the opposition's opportunity and its constraint. Anti-Netanyahu parties hold 67 seats in the 120-seat Knesset, a theoretical majority. But more than a quarter of those seats belong to Palestinian citizens of Israel, and several Jewish opposition parties refuse to sit with them. The arithmetic of unseating Netanyahu remains blocked by the internal ethnic fault line his critics cannot bridge. The damage from Washington arrived on multiple vectors simultaneously. Trump made a last-ditch election pledge to cut $4 billion in annual US military aid to Israel — a figure that translates to 15 billion shekels the Israeli air force commander reportedly described in existential terms. Netanyahu's Friday spin that the cut reflected a "move from aid to partnership" convinced no one in Israel's defence establishment. JD Vance listed "our relationship with Israel" among reasons for Republican voter fury. Incoming Democratic lawmakers made clear that a charm offensive from a new Israeli government would not suffice. Congressman-elect Brad Lander — Jewish, self-described liberal Zionist, detained in the occupied West Bank last month while joining Palestinian olive harvesters — responded directly to opposition leader Yair Lapid's bridge-building proposal. "We aren't starving for a barnstorming tour. We're hungry to see respect for international law and human rights." Lander and two other incoming Jewish members of Congress wrote to Israel's ambassador demanding the release of detained Palestinian journalist Abed Abu Shehada, arrested in a night-time raid by 15 masked security officials without a warrant. The deeper structural problem is that Israel is now losing ground on both sides of American politics. Democrats are conditioning support on human rights compliance. Republicans under Trump are questioning the aid relationship entirely. The bipartisan consensus that sustained Israel's defence doctrine for decades is fracturing from both ends simultaneously. As columnist Ben Caspit wrote in Ma'ariv: "This isn't a process; it isn't happening in stages; it is happening all at once. It is an avalanche." Former senior Israeli diplomat Nadav Tamir offered the most nuanced read: the new Congress will be less willing to equate support for Israel with automatic alignment on every policy, but precisely that conditionality might push Israel toward necessary changes including resolution of the Israel-Palestine conflict. External pressure from allies who see current policy as self-destructive could break the cycle of wars. The paradox is acute. Netanyahu's removal has become more urgent precisely because his US strategy has failed. But the opposition coalition that could replace him remains fractured along the same ethnic lines that define the conflict the new Congress wants resolved. The path to unseating Netanyahu runs through the exact reconciliation his tenure has made harder.
