<<This number ist just adding  Zarya and Zvesda together and you have
ISS. And according to my knowledge they are Krunichev made  and
Krunichev is Russian. So ISS is 90 % Russian.>>

Wow, that's quite an assertion.  OK, let's do the math.

The Russian components to the station, Zarya, Zvesda, and Pirs, add up 
to 92,603 pounds.

The U.S.-built components, Unity, Harmony, Destiny, and Quest, add up 
to 98,970 pounds.

The Columbus module is 28,219 pounds.

This does not count the U.S.-built integrated truss structure and solar 
panels, which come to about 260,000 pounds total.

Correct me if I'm wrong, but I can't seem to make any of the above add 
up to a 90% Russian station.

<<You think the 2 nodes make up more than 10 %?>>

Looks that way. Looks more the U.S. contribution comes in at more like 
like 45% when counting total inhabitable volume (with the Russian 
segments at 42% and the Columbus module making up the balance)  and 
about 75% when counting total structural weight.

<<Columbus is European.  Like I said most of the hardware America 
wanted
to bring they cancelled. They only made the Truss.
Did I forget something?>>

Apparently so.

<<The ATV that was brought to ISS should have been there in  2004.
Everything was delayed or cancelled . But not by the russians>>

But the Russians did cancel a number of planned modules, including the 
Science Power Platform. The only major component outright cancelled by 
the Americans was the centrifuge laboratory.

Just wanted to set the record straight.
