???  I'm not sure if this was a serious suggestion or just a joke.

The SU-35 is, in essence, the Russian equivalent of the Super Hornet.  It is a heavily upgraded version of a 1980's multi-role fighter meant as an interim solution until their next-generation multirole fighter (the PAK-FA) is ready for production.

I'm not sure why we would ever want that as opposed to the Super Hornets, especially given that the Russian jets would be totally incompatible with ever other piece of hardware our air force has and that of almost all of our closest allies.
