US President Trump answered he doesn't trust anyone when was asked if he trusts Israeli PM Netanyahu

Off-the-cuff remarks of this kind from a US president about an allied leader are a soft signal rather than a policy shift, and historically they have mattered only insofar as they foreshadow a change in the bilateral working relationship. The relevant precedent is that friction between Washington and an Israeli government has tended to surface first in personal rhetoric before it appears in anything concrete, such as conditions on military assistance, positions at international bodies, or pressure around ceasefire and hostage negotiations. The transmission channel to markets runs through Middle East risk premia: crude, shipping and insurance costs, and the safe-haven bid, and rhetorical cooling alone has rarely sustained a move without an operational follow-through. What separates noise from signal here is whether the comment is repeated, formalised in a statement, or accompanied by a staffing or diplomatic step; isolated answers to shouted questions have more often faded than hardened. The tells are subsequent readouts from either capital, any change in tone from officials below the principals, and the state of whatever negotiation is live at the time. As it stands, this is colour on the relationship, not a repositioning of US posture.
