A proposal to tie US intelligence and the Pentagon closely to Israel's spy agencies and military is drawing sharp opposition, framed here as a dangerous, hard-to-reverse move.

• Some Republicans are said to back merging US and Israeli intelligence and linking the IDF with the Pentagon.
• The claim is that Trump would not block it because he is too deferential to Israel.
• Others inside the White House are described as strongly against the plan.
• Word is the measure will not pass, but the fear is that once done it could never be undone.

Outlook: The plan may stall in the coming days, but expect a bitter fight over how close US and Israeli security ties should get.
