I'm very tempted to write a fairly short ME story based on what would happen if the canon ME scenario ran into humans who'd kept the Cold War mentality going until that point... Not sure how they'd have actually
survived doing this, but we can put it down to plot armor
Because that would in a way be grimly hilarious; Turians decide to
'punish' the new species for breaking a law that doesn't apply to them, take out a civilian science vessel, and try to invade Shanxi... Only to run into massive amounts of anti-shipping missile fire that takes out most of their drop ships with pinpoint neutron warheads, ground based lasers that punch holes in the capital ships, thousands of satellite weapons that were at one point aimed at each other but now are
all aimed at
them, and if any of them manage to get to the ground, they find the crazy apes are
firing nuclear mortars at them! With neutron bomb warheads small enough to fit several in a backpack. And chemical weapons, and Spirits know what else.
And once all the invaders are dead, the humans go looking for where they came from, with an eye towards making sure they never come back...
Hmm... A fleet of about ten thousand smart bombs with gigaton yields sent through the mass relay network aimed at Palaven? And as they pass through each Relay, a couple of dozen stay behind and nuke it.
It's the only way to be sure, after all
