Governments, if they want, can decrypt any chat
This is not true. Encryption that is not breakable by anyone - including governments - and the tools to use it have been available to everyone for decades now.
It might be broken later (which is why the US stores encrypted messages) but not right now, and is unlikely to be in the foreseeable future.
Interesting article in naked capitalism that contains an info I had not seen before:
Palestinian forces made substantial inroads, advancing into Israeli camps and targeting the 8200th Intelligence Unit among other 11 military barracks. This unit, a linchpin of the Israeli intelligence apparatus, is directly linked to the Gaza Division Command and oversees drones that gather intelligence for Israeli targeting.
The successful attack on this unit, resulting in its destruction and the reported capture or elimination or escape of its personnel, has severely affected the Israeli military’s intelligence capabilities. This setback is evident in the Israeli army’s lack of actionable intelligence.
The unit mentioned has apparently been described as "Israel's NSA". Yet another element showing this was brilliantly planned.
