That's where I'm confused. Isn't Varrick opposed to creating a Super Weapon? What, now that Kuvira's developing one, he'll just make one for Raiko too?
Then again Raiko didn't specifically say "make a Super Weapon for the UR," I think he just said something along the lines of a solution. So perhaps Varrick and Asami are just gonna create something else, like maybe an enhanced version of the EMP that Varrick created when escaping with Bolin and the Earth Empire prisoners.
On the other hand, I imagine the historical parallels would be too tempting to pass up for the creators though...
You are probably correct in the arms race but the only reason Raiko is taking action is because Kuvira is threatening his nation. When he was informed by Team Avatar that Vaatu could destoy humankind he only cared about protecting his country. He is still a self-centered politician.
When did she threaten the United Republic? Assumptions are not facts.
It was the apology of governments during the Cold War.
Yes. Like the Nuclear bomb which US has built in WW 2nd. Then, USSR made another to "balance of power in its favor."
You know I would not be surprised with the brilliant minds of Asami and Varrick they would build the atomic bomb to counter their superweapon as a deterrent.
