Ukraine has been deceived by the West and, as a result, now has to deal with problems. Ukraine did not join the Eurasian Economic Union in the East, but they are not allowed to join the European Union or NATO. Joining them in the near future is nonsense.
The US have violated the INF treaty first, back in 2014, when Washington began deploying Mk41 launchers in Europe, containing Tomahawk missiles. This is a direct INF violation.
Currently, these launchers have been dislocated in Romania and preparations are under way for their deployment in Poland and Japan.
The US State Department issued a detailed rebuttal of Russian allegations of US noncompliance with the INF Treaty in 2018. Moreover, in December 2017 NATO affirmed that the US is in full compliance with the INF Treaty, and that Russia possesses a new missile system that aroused “serious concerns”.
The Romanian Defense Minister Mihai Fifor confirmed back in August 2018 the missile defense shield at Deveslu base, in the southern part of Romania, is not fitted with ballistic missiles.
The Deveselu Navy Support Facility is the first Aegis Ashore Missile Defense Facility placed into operation, providing support to NATO's overall ballistic missile defense (BMD) system. NSF Deveselu’s service members and DOD employees serve as the security and logistic supply line for its primary tenant command, the Aegis Ashore Missile Defense System. The Aegis command consists of a fire-control radar deckhouse and an associated Aegis command, control and communications suite, and housing launch modules that contain SM-3 defense missiles.
