Wall Street Journal says move is part of Trump administration’s effort to get Putin into peace talks

US defense officials have blocked Ukraine from using US-supplied long-range missiles to strike targets inside Russia since late spring as part of a Trump administration effort to get Vladimir Putin to engage in peace talks , according to a report on Saturday.

The Wall Street Journal reports that the Pentagon has blocked Ukraine from using US-made Army Tactical Missile Systems, or Atacms.

Two US officials told the outlet that on at least one occasion, Ukraine had sought to use Atacms against a target but was denied under a “review mechanism” developed by Elbridge Colby, the Pentagon’s undersecretary for policy, that governs how US long-range weapons or those provided by European allies that rely on American intelligence and components can be used.

The review process also applies to Britain’s Storm Shadow cruise missile because it depends on US targeting data, according to two US officials and a British official, the Journal said.
