It would be interesting to see what the geopolitical consequences would be of another nation "helping" a smaller nation become ICBM capable. I know that this was basically the premise of the late Cold War and the Cuban missile crisis, but in all those instances the Soviet Union and United States owned all their missiles - their individual satellite states didn't have the ability to launch them.

But if, say, China were to give away ICBM technology to an ally, for "national security" reasons, so that they could claim plausible deniability...

Right now, Iran has a working ICBM but no nukes and North Korea has working nuked but no ICBM. The nightmare scenario is that they swap kit so both has both. That would make them both untouchable. Nk is crazy enough, they'd demand cash (and fuel and food) not to just press the button and likely get it.
