CMV:The Jaegers from Pacific Rim are an incredibly bad solution to the Kaiju problem

EDIT: Shit, edited the wrong post

First, let me get this out of the way. I understand that this is a movie, and that the idea of giant robots fighting monsters is a far more appealing concept for a movie than a destroyer shooting a missile at them.

That said, the Jaegers are an awful solution to the kaiju problem. There are other methods which would work far more cheaply, easily AND effectively than a gigantic, expensive robot that only a few people in the whole world can crew.

For example, we see Striker Eureka employing anti-kaiju missiles in the film effectively. Since these missiles exist and are proven to be effective, I have to question why the jaeger is necessary. Why can't these missiles be fired from ships, vehicles or airplanes? 

I understand that kaiju are evasive and fairly quick for their size, but we already have cruise missiles that can travel at over mach 7, and targeting systems capable of hitting targets far faster, more evasive and smaller than any kaiju. 

Instead of, say, attaching these effective warheads to cruise or ballistic missiles, we instead build gigantic, expensive, hard to crew, hard to produce and frankly not that effective robots. 

That's not even mentioning the plasma cannon, which could also be employed without the Jaeger. Something like a gigantic tank with anti-kaiju missiles and a plasma cannon would be a superior weapon to the Jaeger in just about every way.

I don't necessarily disagree, but the explanation they gave was that the carcasses of the kaiju were extremely toxic to the environment, so they needed to be killed with blunt trauma that left them in one piece rather than with explosives which would spread their remains around poisoning everything.  So the solutions was to create essentially giant rock-em sock-em robots that could punch them to death. The more destructive weapons on the Jaeger's were mostly used later on once the kaiju became too powerful to kill using brawling tactics.

Granted, all that is said with the sort of wink and nod from the narrative whose actual explanation for the Jaeger's existence is more like, "because it's totally fucking awesome," but they at least gave a half-hearted effort to make sense of it.
