World War 3 question

[Timelord]

The days of massive mega tonne warheads mostly died with the end of the cold war. All the modern warheads are smaller. This is because they don't need 3 massive missiles to target one city because back then they were so inaccurate by up to 10 miles. In modern times they can hit a rat through a barn door. So targeted strikes are now the Western style military doctrine, so as not to completely destroy the country being warr'd with. That is for invasion purposes and control of a vanquished foes resources. A complete wasteland is not much use to anyone. Of course they could just send much more than necessary or to negate ones that are shot down. Anyway, ouside the cities, survival was much more possible. 2 weeks after the initial blast, local conditions pending, it would be possible to leave a shelter for short periods. This quickly extends in time as the weeks roll by. The biggest killer in our modern constructed environment would initially be firestorms in urban areas and later starvation for the majority of survivors countrywide. You could call it a "Double Dip" Cessation. lol. The data is all there from 2ndWW blitz and Jap atomic studies.
The note I really wanted to post is that for Scythe13's query about Iran not being in our news. Try watching RT news or looking up the RT website and you will get daily info on Iran & Syria + more.
