In addition, some time before the Tselina-D was shot down, Russia officially declared that the tests of the missile complex did not pose any threat to the ISS.
According to military expert Dmitry Litovkin, this all happened due to the US withdrawal from the ABM Treaty (treaty on limiting anti-missile defense systems). This agreement contained a clause according to which it was forbidden to create mobile missile defense systems. Also, according to Litovkin, Russia now has several similar missile systems: these are the S-500 and S-550. The first is designed to hit close targets, and the second – long-range. In America, work is underway on such weapons, but they have not yet achieved significant results. According to the expert, it is for this reason that the Pentagon is so scared that Nudol was able to shoot down a satellite.
