Answer: Because you want to get the job done
fast.
Nerve agents and other battlefield chemicals are
an area weapon. Be it town or trench where your enemy is hiding, your deadly
gas will find them.
From the waterlogged northern European plains of
World War I to the arid mountains and marshes of the Iran-Iraq conflict,
chemical weapons have been used when armies get bogged down and commanders get
frustrated.
When the urge to win outweighs warfare's cold
calculus of routine slaughter and indignity, the danger is a slide into the
depravity of craven criminality.
Adolf Hitler used them in his extermination
camps, diabolical in his annihilation of his enemies. So when I heard from two
separate sources close to Syrian President Bashar al-Assad's thinking that he
planned to retake the country's largest city Aleppo in a "swift battle of
high causalities" so he could go to peace talks in Geneva with "facts
on the ground" in his favor, the use of chemicals in Damascus' suburbs
against resurgent rebels made sense.
Criminal Assad know how effective it is… he will use it
again again…why shouldn't’ he? Job done easily…. and cheap economical... Russia knows very well...
