We need to pre-position something to knock it down but the high loft liftoff and the far north location it is in DPRK near the Chinese border, makes it very difficult to get in range for what we have to bring it about.
No need to shoot down the NK missile lofted over Japan.. A few air launched cruise missiles via B1 bombers out of Guam will punctuate Kim’s supposition that its the same old 50 year crap, completely leveling what ever launch site he uses.
PDJT has kindly met with Kim twice and Kim is playing games? Now the brass knuckles come out.
