I only persist because I see your Gadsden flag-themed logo and assume you're no fan of governments. I'm having trouble understanding exactly what exactly you're doubting since you seem to know that governments do bad things.
My position is that if a big bomb exists that could do this, having such a sociopathic government is a surefire recipe for it getting used and therefore starting armageddon.
The only thing keeping nukes from flying at each other is MAD game theory... And our leaders don't seem competent enough to me to respect that anymore.
