If your communications are vulnerable, and your communications are of interest to governments, then there's very little you can do to avoid it being intercepted. You may, if you trust your hardware, your encryption software, and your key management, be able to keep that intercepted message from being read for some length of time. That is different than actually intercepting the traffic, which is trivial for the organizations we're talking about, and there is very, very little someone can do to avoid the interception. Believing that being on a different continent makes you safe is deluding yourself.
