The US–Israel alliance faces growing political challenges within Donald Trump’s own support base, according to international relations scholar Professor Yossi Shain. In an interview with 103FM reported by The Jerusalem Post on 4 November, Shain warned that opposition to Israel among prominent MAGA voices could weaken the relationship’s political foundations.
What the expert warned
Shain argued that the relationship has traditionally rested on two foundations: shared values and strategic cooperation. In his assessment, both face increasing challenges as American political debate focuses on whether support for Israel serves US national interests.
He connected those tensions to the wars in Gaza and Iran, saying disagreements now extend beyond the Democratic Party into parts of Trump’s political movement. He also stressed Israel’s security contribution to the United States and the importance of preserving the partnership.
What polling tells us
Research conducted earlier this year provides context for that warning. A Pew Research Center survey of 3,507 US adults, conducted from 23 to 29 March and published in April, found that 60% held an unfavourable view of Israel, compared with 53% in 2025.
Republicans and Republican-leaning independents remained more favourable than unfavourable towards Israel overall, at 58% versus 41%. However, 57% of Republicans aged 18 to 49 expressed an unfavourable opinion.
Those findings show an important age divide within the Republican electorate. They measure opinion from March, rather than sentiment this November, and cover Republicans and Republican-leaning independents broadly rather than a separately identified MAGA group.
Why the distinction matters
A public opinion survey and an expert’s assessment answer different questions. Pew’s findings describe how respondents viewed Israel; Shain’s warning concerns the potential consequences of political divisions for the alliance.
Together, they suggest that support for Israel deserves closer attention within Republican politics. They also show why the movement cannot be treated as holding a single position: the survey found continued majority Republican favourability alongside substantial younger-voter scepticism.
Impact: watch decisions as well as rhetoric
Shain’s assessment raises a practical question for Israeli and American policymakers: whether disagreements within Trump’s political camp will translate into changes in policy.
The consequences would depend on decisions about assistance, diplomacy and military cooperation. For readers following the relationship, those decisions will provide firmer evidence of its direction than individual comments alone. Shain’s central warning is that maintaining the alliance requires attention to its political support as well as its strategic value.
