Definitely reads as a dig at Kissinger, the kind of dig you make when a person's sexual escapades are an open "secret". Gossip gets around.

The "they will create disasters" part is definitely boomer "hurr hurr wahmens" though, common attitudes and jokes of the 50s that were simply not examined for being the problems that they were. Doesn't take away from the fact he was progressive on their liberation, progressive on their inclusion in the workforce equally, etc etc. Well ahead of capitalists of his time just as we today are well ahead of capitalists of our time but very likely not without our issues or blindspots that future leftists will criticise.
