If it landed near Japan then it’s not an ICBM.
It has been confirmed to be.
If you can throw a football fifty yards down field, how far will it go if you throw it nearly straight up?
Megan is technically correct.
It is not an “Intercontinental Ballistic Missile”, it’s an IRBM - Intermediate Range Ballistic Missile.
The fact that its trajectory is highly eccentric with a subterranean perigee means that it’s a ballistic missile, just not with the long range needed to move between continents.
But it’s close, and possibly scalable to a multistage ICBM.
Solution: MOAB their entire launch site and manufacturing infrastructure.
Don’t apologize.
Don’t worry about China’s response. They won’t start WWIV over it.
