I don't see why. You said the Avengers are connected by war. The Justice League is also connected, but by tragedy. Superman's home planet exploded, Batman's parents were murdered, Wonder-Woman's people were enslaved, Flash's mother was murdered and his father was framed, Green Lantern's father's plane crashed and his mother had cancer, Aquaman's parents died, J'onn J'ozz's homeworld was devastated by a virus and etc. And the Avengers also have different M.O.'s and backgrounds.
The personal losses of the J.L.A. aren't all related to fighting crime or upholding the law. Superman may feel alone but DC has written him as being raised on Earth. His values aren't Kryptonian but those of Ma and Pa Kent. That loss is not similar to Bruce Wayne's nor the Martian Manhunter's.
When I wrote that many Avengers share a history with war, I meant they know exactly war does to the world. Many of them have fought in war, or done work that's related to the scale of war. If they have to unite to stop a great threat they'd know well what it takes to get it done and why it must be done.
And the Avengers did? (Grow up alongside other heroes?)
Many of them did, in their training or in their personal battles. Thor has fought for centuries under his father, Odin the All-Father, with the Warriors Three, and the rest of the Aesir. Captain America fought alongside many brave people during World War 2, including heroes like Logan, the Invaders, the Howling Commandos. The Black Widow was saved by Captain America and Logan back in that war. Her own experience as a Soviet spy gives her insight on the results of cloak and dagger tactics.
Every group has. It's how they managed to outcome their personalites and bond that makes them a real group, as JLA: Year One showed us.
But I trust the Avengers more as a stable team than the Justice League.
Same with Black Widow and Scarlett Witch.
They don't have Amazon charged pheromones. Drives men wild.
I didn't understood that part. You think the JLA should be authoriarian (Like Authority?) to make big decisions? The Avengers aren't, and their decisions are as big.
There's little in their background to prove they have the right to get involved in world conflicts other than their great power and infinite growth of supervillains. Thor isn't just Midgard's protector because he's simply a thunder god. He was once worshipped and he's fought many monsters on the planet centuries ago. His background gives some precedence. Captain America was created by order of the U.S. government during World War 2. Black Widow served the Soviet regime. Tony Stark becomes Iron Man for many reasons, from combating hi-tech crimes to exploitive industrial military complex he's a part of. Nick Fury also serves the government.
Their abordages might be difference, but their protocols are the same: Protect humanity. That's what connects them.
Yes, but their mandate isn't very clear. I can trust them to fight a League of Supervillains, but under who's authority do they have to get involved in problems besides supercrime and natural calamities?
I don't quite remember him doing that, but OK.
He said it in the Heaven's Ladder story. Ironically those there good times.
Help the innocents, I'd say.
Yes, but under what mandate and authority do they have to cross borders so freely? What if their efforts hamper one society's own methods of helping victims? What if one area doesn't even need their help while another is completely missed?
They save Earth on a monthly basis. They saved the whole Universe a good number of times. They focus on social issues, like hunger, war and etc. They fight the never-ending battle, as Superman says.
Evil will always exist. Make a costume and commit crimes is easy. (There's a character, the Calculator, who sells deceased villain's equipments, costumes and weapons to average criminals for money.)
That is the tragedy of an on-going serial. The world can't handle countless destruction on that scale. Civilization would be set back, regardless of their wonders. Comics need to have another revamp because their worlds aren't doing so well.
Much as the League. Superman has infinite power in his hands, and yet, never lost control. Batman walks on the fin line between heroism and vengeance. Wonder-Woman is a speaker of the peace, but has a background in war. The Flash deals with the seduction of the speed and secrets withim the Speed Force. Green Lantern must protect 140 planets and is tormented by the sins of his past. Aquaman lives with the burden that one half of his inhiretance is poisening the other. J'onn J'ozz is alienated. An stranger in an strange world. Etc.
I recommend Kurt Busiek's
Justice League/Avengers. It's a great analysis of both teams, their mistakes and their accomplishments. Great read.
OBS: Sorry for the misspelling. I'm not american.
I have Busiek's JLA/Avengers. I loved it. But as far as teams go, I have more trust in the Avengers. Since many of them have a history with war, they're more familiar with the amount of power needed do act. Going back on the issue of their authority, I think their backgrounds could give them better right to unite as a force. Superman is descended from one of Krypton's ruling families. Wonder Woman is a princess. Batman is a billionaire. Aquaman is a king. Martian Manhunter was a cop on Mars. Flash works for the police as Barry Allen. Hal Jordan served under the airforce. Despite that, I see a group of superhumans who united by their own decision without permission of recognized authorities. That's insane. At least the Avengers have a liason with the governments.
