Here's part of an article:
Experienced envoys have retired or resigned in droves. John Feeley resigned as ambassador to Panama on March 9th. He is no "squishy hand-wringer". A former Marine helicopter pilot, he oversaw cartel-busting operations as deputy chief of mission in Mexico..
I don't understand what it means when squishy and hand-wringer are combined together. Somebody who likes to wring his hands?
"Hand-wringing" means worried talk/behavior, perhaps somebody who doesn't show worried behavior?
