"I would just say to everyone: anyone who thinks that is a 'silver bullet' for this war — does not understand what is happening in this war. It is not a 'silver bullet — one additional capability, but where this war is being fought is on basic munitions, and then the question of manpower," he said during a speech at the Reagan National Defense Forum in California, speaking about the transfer of long-range missiles and strikes deep into Russia.
According to Sullivan, for the United States, the problem with the transfer of ATACMS was the size of its own arsenal, and when Washington accumulated a sufficient number of these missiles for sending, it transferred them to the Ukrainian Armed Forces.
