The Israeli government is preparing to request parliamentary approval to increase the defense budget significantly amid ongoing security challenges. In a special Knesset session scheduled for the coming month, lawmakers will vote on expanding funding for urgent weapons procurement for the Israel Defense Forces (IDF) from 70 billion shekels (approximately $20 billion) to 90 billion shekels ($25 billion). This adjustment would raise Israel’s overall annual defense budget to an estimated 184 billion shekels, or about $61 billion.

This proposed budget increase reflects the country’s recognition of a deteriorating and complex security environment. Officials cite persistent threats from Iran, Hamas, Hezbollah, and the Houthis, with 2027 anticipated to be another year of multi-front military confrontations. Israel also faces uncertainty on the eastern border and ongoing unrest in the West Bank, while diplomatic tensions extend to Turkey, which has made hostile statements toward Israel. These factors are driving a reassessment of defense funding, deemed essential regardless of the government elected in Israel’s upcoming fall elections.

The expansion of Israel’s military budget marks a continuation of a decade-long trend of increased defense expenditures, with spending expected to nearly double over the next ten years. However, officials acknowledge that no fully identified funding source currently exists to cover the surging costs. This fiscal pressure may lead to budget cuts in other government sectors and the imposition of new taxes.

Israel’s recent security situation has been shaped, in part, by strategic decisions made over the past decade. Between 2013 and the subsequent years, under then-Chief of Staff Lt.-Gen. Benny Gantz and Defense Minister Ehud Barak, the IDF adopted a multi-year plan that reduced ground forces’ funding in favor of investments in the air force, cyber capabilities, special operations, and intelligence. Successive defense ministers, including Moshe Ya’alon and Avigdor Liberman, maintained similar priorities. This shift contributed to a decreased readiness for extensive ground warfare, a vulnerability exposed during the 2023 Hamas conflict.

The prolonged fighting and defense efforts since late 2023 have generated direct military costs of approximately 400 billion shekels ($134 billion), excluding humanitarian and rehabilitation expenses. The toll includes medical treatment and mental health support for about 15,000 injured soldiers, as well as aid for 2,000 families who lost loved ones. Additionally, support is required for civilians displaced from southern and northern regions and for reconstruction of affected communities.

In response, Israel has committed to strengthening its military capacity and achieving greater self-reliance in defense production. Prime Minister Benjamin Netanyahu unveiled in late 2025 a plan to invest roughly 400 billion shekels ($133 billion) over the next decade to develop an independent arms industry, a figure that has grown from initial estimates. Recent contracts include partnerships with companies such as Elbit Systems, Rafael Advanced Defense Systems, and Israel Aerospace Industries (IAI) to increase production of munitions, missile defense systems like Iron Dome and Arrow interceptors, and the advancement of indigenous armored vehicles and naval vessels.

Israel is also pursuing international collaborations to diversify its arms supply chain, including co-production arrangements with India, intended to reduce dependency on U.S. military aid. The country is advancing new technologies such as the Iron Beam laser air defense system, backed by a $500 million initial contract, with potential for further investment if the system proves effective.

Defense spending now accounts for nearly 9% of Israel’s gross domestic product, making it the second highest military expenditure ratio worldwide. This rise in costs coincides with efforts to recalibrate the U.S.-Israel security relationship. The existing 10-year memorandum of understanding on U.S. military aid, which expires in 2028, is expected to be replaced with an agreement fostering reciprocal defense production and joint technological development.

U.S. legislation for fiscal year 2027 introduced the “US-Israel Defense Technology Cooperation Initiative,” emphasizing collaboration on artificial intelligence, quantum computing, directed energy, and autonomous systems. Analysts propose phasing out traditional U.S. military financing gradually while expanding joint research, co-production, intelligence sharing, and military integration. Discussions include the possibility of a modest U.S. military presence in Israel and enhanced regional cooperation.

Advocacy groups in the United States support this strategic shift, arguing that closer integration and deeper defense collaboration will benefit both countries’ security and economic interests. Proposals involve extending financial assistance while establishing a “Model Ally” framework to strengthen industrial bases and supply chains. Some call for increased U.S. military assets stationed in Israel and even a limited mutual defense treaty.

Israel’s high-tech economy and defense industry development underpin the feasibility of these transformative changes. The evolving partnership aims to reinforce Israel’s strategic standing while mitigating vulnerabilities to international embargoes and political pressures, ensuring long-term preparedness amid a challenging regional security landscape.
