We are not safe anywhere. Trust no one.

And as long as CPUs are designed in USA, I myself assume there are backdoors inside CPU which are triggered with some data pattern which can come from anywhere (net,usbstick,program,datafile) to L2-cache and recognized by the circuity. After that CPU's secret OS-detection routines inject backdoors to any closen or open source operation system. So just sending suitable IP-packet to some IP-address will get the target machine owned, and no firewall or virus-protection will help.

We know, starting from Pentiums, there is parts of the circuity on the CPU which does not seem to have any function and number of transistors have multiplied since then.

It would be cost effective, so would be stupid NSA not to do it. Practically all CPU's are designed in USA, doesn't matter where they actually are made after that - noone will debug current huge and complex circuity by reverse engineering.
