ICBMs In Belarus and Ukraine?
 

Does anybody know the numbers and types of ICBMs the Soviets lost when these two nations became independent?

None. As part of their separation from the USSR; They were required to surrender ALL Nuclear capability (overseen by the UN) and significant chunks of their strategic military assets such as Radar, Air Assets in the region, and Command & Control. Belarus, The Ukraine, And all of the Baltic States were completely stripped of ALL strategic assets during their transition in the 90's.

They didn't surrender them overnight however. After the initial collapse, according to Wikipedia, there were 130 SS-19s and 46 SS-24s (using the DOD designations here) in Ukraine, as well as 33 heavy bombers, including some Blackjacks. The heavy bombers, plus the Backfires, were either scrapped or sent back to Russian as debt payment.

From what I remember they transferred them back to Russia starting in 1994 and they were all gone by sometime in 1996 - but at the time they broke away they had over 1700 warheads on Ukranian soil between the missiles and bombs for the bombers

And no doubt now wish they had kept a few hundred.

Maybe; that said, they'd be of little practical use in fighting this particular war; the Tu-22Ms are of little use in insurgency wars unless you want to carpet bomb people and that kind of looks bad.

It is also entirely possible to invade the territory of a nuclear-armed state and not invite a nuclear response because everyone knows it would be completely ridiculous to do that i.e. a certain war in the South Atlantic.
