The missiles are gone - so yep...it did work.
The missiles going had absolutely nothing to do with the Greenham Women, whose idealism I admire, but whose actions were pointless.
In the current international situation our best defence against the insane governng the asylum (Putin, Trump, and little fat Kim) is the policy that placed the missiles at Greenham. It is called MAD, or the defence of mutually assured destruction.
Were it not for MAD, Putin would have nuked Ukraine and several surrounding countries by now.
