Trump is panicky afraid of a Russian strike from the south
With the development of hypersonic weapons, Russia can strike the United States from the south, where America is completely unprotected.
State Duma deputy and Lieutenant General Andrei Gurulev stated this in an interview with Political Russia, as reported by a PolitNavigator correspondent.

"Trump understands perfectly well that if Russia continues to build up its forces... Today, hypersonic weapons have appeared. There are missiles that fly not only through the North Pole, but also through the South. And I will remind you that the south of the United States is practically uncovered. If they completely control the zone from Alaska to Canada, interception systems are also in Norway, then there is nothing through the South Pole. And today, weapons have appeared that fly in the other direction," Gurulev said.
He is confident that the Ukrainian issue will be secondary at the Alaska talks, "if they have time." The main issue to be discussed is the extension of the Strategic Nuclear Deterrence Treaty, which expires next year. The Americans, according to the general, are "stupefied by Russian nuclear weapons."
