The problem is Team Rocket will never win unless they turn good, evidence to support this: Pikachu Revolts, The second movie, The meowth island one, We're no angels and others.
But i recon James should stop being such an idiot worshipping [SPOIL]Manene/chimecho [/SPOIL] and give some support to his Team. I don't like how James acts like hes better than Jessie and Meowth cos if anything he's worst, he knows what he is doing is wrong and does it anyway, Jessie and Meowth don't know any better.
If they unite and stop fighting they could improve.
Also if they just bought a shotgun i think they'd have a better chance at getting ash to give them pikachu, lol
No way could they ever split up Team rocket, then the lil pun with there names wouldn't work anymore.
Its one thing to split up Team Twerp and swap them round. but it would be just to sad to split up Team Rocket, Jessie James and Meowth all contribute to creating one big character really, and if they split them up gahhh it would be terrible.
Plus james is Jessie's Thirteenth partner, and he promised her she could trust him and that he's never let her down. (sltho hes broken that a hundred times)
Jessie is the deeper character in team rocket cos under her evil exterior she is just really vulnerable, i mean the poor girls had a rubbish life her mother crushed in an ironic snow related death, twelve useless partners, no one ever treating her nicely (with the occasional exception of James and Meowth), and failure after failure even when she plays fair (princess vs princess, [SPOIL]Pokemon Conference, Yuzirha contest.[/SPOIL], Ignorance is Blissey)
And her vulnerable moment in "We're no angels" when she says "Oh oh no" in a shakey voice at looking at James and Kate.
So in conclusion they should no way be split up, its J and J and Meowths destiny to be together and no one should come between that
