For years now, Russia has bought cheapo attack drones
from Iran in huge quantities to bolster its war on
Ukraine.
Suddenly, this won't be possible.
It's major military loss.
Will Russia DEFEND Iran ? Probably NOT.
However it's NOT going to be happy.
A FEW defenses MAY be offered - mostly to
inconvenience the USA/West. The USA most
likely plans attacks on one or two deeply-
buried Iranian bomb factories. Russia KNOWS
this, knows where they are. A few advanced
surprises for B2s may lie in wait ....
They're not entirely 'invisible' ...
Embarassing/inconveniencing the USA on this
front WOULD be useful for Russia.
