No, you must wait for him to fire, then try to fire your gun within microseconds in just the precise way that your bullet hits his bullet before it strikes you and kills you. However, should he successfully shoot you, and you survive in some maimed state, you might then be permitted to shoot back, but you MUST above all else make sure that the caliber of your gun is not larger than his, otherwise your defensive response would be "disproportionate", which is deemed the worst thing imagineable in the modern concept of self-defense.
Seriously, it was endless talk, talk, talk that got us into this sorry position, yet now we are actually lectured by some of the same people who advocated for the past endless talking, and told that we now have no viable military option because too many people in the two Koreas would be killed. That's nice. So essentially the purpose of diplomacy was to delay the plainly necessary action long enough that action was no longer feasible.
I reject all of that nonsense, along with the equally pathetic hand-wringing over what China or Russia would do if we launch a military response. Those are just more excuses for endless paralysis, which is exactly what Russia and China are using North Korea for. NK acts as their proxy to threaten and possibly attack us, all the while using the threat of a larger war to keep us from defending ourselves.
If we allow ourselves to be cowed by this travesty, we will never be able to find the will to defend our national security again. It's time to smash that pathetic little idiot, and send an unforgettable message to the other communists as well. Then there's the matter of Iran....
Tomorrow we are deferring our ability to act to the security council where Russia and China have veto power.
Aren’t you supposed to turn and run away?
[That seems to be the policy, thus far. Let’s wait for China to do something.....*wink wink nod.*]
