Purely from an opsec perspective I doubt we'll ever have world leaders as online and accessible on private platforms like Twitter as we did in the last years.

Purely from an opsec perspective I doubt we'll ever have world leaders as online and accessible on private platforms like Twitter as we did in the last years. It's just too much of a national security risk and every major state has to assume the CIA/Mossad/KGB/etc. is actively trying to intercept and undermine world leader's online presence. It is stupidly easy for a determined state actor to over time infiltrate and get an in with a private American company. The risks are just too great to have a world leader using Twitter or similar platforms for anything more than reshashed press releases and announcements. Smart nations will probably get ahead of potential hacking or other incidents by just having a blanket and clear policy that no official business will be communicated or done on Twitter or similar platforms.
