Let's clear a few things up...the 2.0L Ford ZETEC and the 2.0L Mazda FS-DET are COMPLETELY different, INCLUDING THE BLOCK. If anything, the Zetec is a tougher motor than the ancient FS(which btw was originally a truck motor)....The new 2.3L Duratec and the Mazda 2.3L MZR are basically the same, with a few small differences...The Protege is definitely a better handling car than the Focus, in basically EVERY similar trim DX>SE, ES>ZX3,P5>ZX5,MSP>SVT....
Ford owns exactly 33.4% of Mazda, exactly what Japan requires to have CONTROLLING interest in a company, which is not full ownership, but just as good, because it's cheaper, but still allows you to have the final say so...And if Japanese law changes and requires a higher amount to have controlling interest, Ford WILL up the ante right along with the law.
The European Focus we are NEVER getting.
