The US support has persisted through periods of tame criticism from successive administrations of Prime Minister Benjamin Netanyahu's military offensive in Gaza, repeated violations of the ceasefire reached last year, and roadblocks to a more lasting peace, according to Al Jazeera.
At least 74,243 Palestinians have been killed in Gaza since the Hamas-led attacks on southern Israel, which killed at least 1,139 people. At least 1,460 Palestinians have been killed in Gaza since the October 11, 2025 ceasefire took effect, as Israel has continued to expand its area of control.
Josh Paul, a former US State Department official who now runs the lobbying firm A New Policy, described the support as unconditional.
"The bottom line is that under both the Biden administration and the Trump administration, the US has continued to provide unconditional support for Israel, both in terms of finances, arms transfers and other forms, such as diplomatic support," he told Al Jazeera.
"That's before we start adding in the costs of America's wars in the region, whose causes are greatly attributable to our support for Israel and to Israel's actions."
The United States has provided nearly $300bn in aid to Israel since its creation in 1948 when adjusted for inflation, more than any other country. A 2008 law requires the US government to assure Israel maintains a so-called Qualitative Military Edge over its neighbours. The war has been described by critics as genocide, and Al Jazeera has reported on a UN inquiry that found Israel's deliberate targeting of children in Gaza was part of genocide.
