Under no scenario will cuts to offensive capabilities happen, it doesn't matter which party or person is in the White House.
Real US cyber offensive spending is buried inside of the three letter agencies and buried in classified spending segments within the budget (the $50b to $100b black budget), not out in the open in the supposedly transparent defense budget. It's very silly anybody would believe the US would cut its spending on cyber offense, while it's deep into a never-to-end cyber conflict with Russia and China; a conflict which none of the parties are much attempting to keep hidden at this point.
All my searches are only turning up the most recent news about the most recent pipeline hack, but I seem to recall reading that the US hacked/sabotaged an eastern European oil or gas pipeline decades ago.
