We hope! After the clinton years and all the spies we caught, I’m not completely sanguine that far more didn’t leak out than we’ll ever know.
I wouldn’t be completely astonished to find out that we had deliberately shared details of our safeing and PAL mechanisms with Russian and China, in the interests of making their weapons “less likely to catastrophically fail and trigger a war”.
All PAL designed in America stays here.
The Chinese and Russians have “designed” their own more or less.
