Russia’s SU-35: Mystery Fighter No More
I'd say yes, if we had to take them on that is.
Otherwise, i'd just say it's a fairly sensible idea from Russia to bolster jobs and industry in a recession - with our bunch would do the same, order more T45's, get a License for Blackhawks for Westlands to produce (or type of your choice)
But that would mean increasing the defense spend.... heaven forbid, I mean we're only at War FFS...
