Actually one of the main reasons I want TTIP not to happen is because I don't want any closer relationships with the USA. US foreign policy has been somewhere between awful, irresponsible and plain evil for the last couple of decades. Don't get me wrong, it is not unreflected anti-Americanism, I am German and hugely thankful for what the USA has done for Germany in the past, especially of course during and after World War II.
But that changed. I would love if we could distance ourselves from the USA for a multitude of things from spying over torturing to the offensive war against Iraq, to just name some obvious examples. If we as Europeans impose sanctions on Russia right now for their actions related to the Ukraine, we should have imposed sanction on the USA long ago.
But we can not because we are so dependent on the USA, especially when it comes to IT with most of the major players like Microsoft, Intel, Google, IBM and Apple being US companies. We would be screwed without them. Could we openly oppose the USA and still do business with them? Maybe. Do we want to find it out, test who gets hurt more? Not really.
In the same way the USA is doing business with regimes like Saudi Arabia we keep doing business with the USA. But I am convinced we should really avoid getting even more entangled with the USA wherever possible to not risk worsening our position further. At least until US politics gets sane again.
