Am wondering with all the sanctions being imposed on Russia, I am wondering why isn't Russia also imposing sanctions on the USA as well, am sure it will be payback on them for doing things like this without proof.
In certain sectors, Russia is dependent on the American / Western technology. But you should also remember that on certain other sectors, the Americans are dependent on Russia. For example, without the Russian technology, the International Space Station (ISS) would have never got completed. And without the Russian rocket engines, the Americans won't be able to transport their astronauts to the ISS.
Plus, it looks much cooler if we have effort of all humanity gathered in one place tohelp us conquer the space. Russians don't have anything crucial or impossible to replace.
Joining forces with Russians is more like Public Relation publicity stunt more than anything else.
