It is a lucky fact that for the past 10 years huge investments have been made in securing infrastructure inside the United States. That's not to say we aren't assailable (look at Natanz - it was an air gapped network; or better yet look at the attacks on US infrastructure we do know about). Washington has compared cyberwarefare to Basketball rather than Soccer. In Soccer the offense and defense are mostly matched and the team to score those few big shots take the victory. Cyberwar isn't like that. Cyberwar is like Basketball. The defense can only slow the offense - and the victor is the team that scores more points, more often. I do not know about the implication about wars being fought on the homefront. As far as kinetic warfare it seems less likely - but yeah when it comes to cyber essentially every country has a home there. One more note. The military, from this year onward, is investing in something known as red teaming as a standard process for military R&D. Red teaming is the active no holds barred exercise where hackers are set loose on a target while a blue team tries to detect, mitigate and expunge them. Red teaming will now until forever be featuring in the development of new US weapon systems. Everything from RPGs to tanks and helicopters to drones to radar to radios.
