Quite a number of U.S. embassies had HF backup until the mid-1990's. 
Most of them in the third world have SSB "Emergency & Evacuation" gear, 
but none for the record traffic circuit.  There's so much demand for 
bandwidth these days.  There's a need for ISDN voice circuits, e-mail 
and even video/imaging.

Most U.S. embassies used open wire fed dipoles with KW-rated, 
nitrogen-filled autotuners.  Many foreign embassies use/used cage 
dipoles with open wire line.  It was seldom that you'd see any type beam

It may have been, but it wasn't used by the U.S. Department of State. 
Our SSB gear changed in the 1980's from Collins to Transworld.  In 
J5-land, I had a Paragon at home and I tried to wear it out making 75k 
or so QSOs as J52US.  It made another 65,000 at 9L1US before being set 
aside for an Omni VI at A22MN.

Nope.  The Swedes in Guinea-Bissau used a large LP with a Drake TR-7 and 
L-4B.  Then again, all of their traffic was sent in the clear too.
