[Samurai Jack] Why didn’t Aku just nuke whatever location Jack was at?

He came up with all these hair brained schemes and sent God knows how many assassins but he never went the Nuclear option. It’s not like Aku would care what people thought of him afterwards since he’s the Shogun of Sorrow. As a matter of fact he would probably revel in the newfound fear of everyone knowing he could just eradicate any location he wants in an instant. 
Jack may be able to fight off assassins and otherworldly beings but he can’t really survive an island sized explosion with a follow up of nuclear fallout.

He did once. In the Spartan episode a city sized robot exploded next to Jack, and he was fine and suffered no ill consequences.

Ranged weapons are just much less effective in the Jackverse for some reason, as are explosives. A sword or spear is vastly superior at killing people.
