America wasn't waging covert war against Russian infrastructure in 2015.

Timeline is not relevent to current political war situation.

Squirrel damage is limited to a short out.

Human damage can break many many obscure parts with a single bomb.

Not even remotely close comparison in terms of damage.

"there have been eight deaths attributed to animal attacks on infrastructure, including six caused by squirrels downing power lines that then struck people on the ground."

75%!
