Regarding the reasons why and how Ukraine ended up being defenseless against missile and bomb attacks on its cities and civilians from the side of Russia, Belarus and the Black Sea, we need to make a brief digression into the history of independent Ukraine.
In 1992, the Ukrainian Air Forces had 1,100 combat aircrafts. For now, we will consider just the missile-carrying aircrafts, which could strike at the aggressor (the Russian Federation) even without entering its airspace (missile launch range of about 2000 km).
Only in its army missile aviation fleet alone, Ukraine had about 30 Tu-16, 96 Tu-22 aircraft of various modifications (including reconnaissance and electronic warfare), 23 Tu-95, and 19 Tu-160, as well as arsenals of air cruise missiles X -55 (1068 units) and X-22 (423 units). In addition, Ukraine received 3 regiments of Tu-22 and Tu-16 naval missile carriers from the Black Sea Fleet.
During the presidency of Leonid Kuchma, under active pressure from the US State Department, 60 Tu-22 missile carriers, 10 Tu-160s, and 19 Tu-95s were dismantled. On top of that, 487 Kh-55 cruise missiles and 423 Kh-22 cruise missiles were destroyed.
In 1999, with the consent of the United States, Ukraine handed over its 8 Tu-160 strategic missile carriers, 3 Tu-95 missile carriers, and 581 X-55 cruise missiles to the future aggressor - Russia.
NOW EXACTLY THESE AIRCRAFTS ARE LAUNCHING MISSILE STRIKES ON THE CITIES OF MARIUPOL, KHARKIV, KYIV, VASYLKIV, SUMY, CHERNYGIV, VINNYTSIA, DNIPRO, IVANO-FRANKIVSK AND OTHERS, KILLING THOUSANDS OF CIVIL RESIDENTS AND DESTROYING HOUSES AND HOSPITALS.
In 2001, Ukraine sold 12 cruise missiles to Iran and 6 units to China. 7 Tu-142 anti-submarine aircraft were also dismantled, and now Russian submarines are launching attacks with Kalibr missiles from the Black Sea.
Thus, under pressure and persuasion coming from the United States, Ukraine COMPLETELY DESTROYED its missile-carrying aircraft and air-launched missiles worth tens of billions of dollars, WITHOUT GETTING ANY COMPENSATION. This allowed Russia, the aggressor state, TO LAUNCH BARBARIAN MISSILE ATTACKS ON THE CITIES OF UKRAINE on a daily basis and with impunity, FORCING MILLIONS OF PEOPLE TO LEAVE THEIR HOMES AND MOTHERLAND.
But these destroyed weapons were not nuclear and did not pose a threat to the United States. If Ukraine had not succumbed to persuasion and had not destroyed its missile-carrying aircrafts, Putin would never have sought war with Ukraine. Crimea and Donbass would still remain part of Ukraine and millions of people would not flee the country in panic.
We believe that the Administration and Congress of the United States are obligated to urgently provide the people of Ukraine with the necessary means of Anti-Missile and Air Defense to prevent the unpunished massacre of the Ukrainian people and destruction of their cities.
