We haven't technically had an official war since WW2. Every "war" was a special military operation. So this is business as normal because no president wants to have to go through Congress to declare war officially. But hey why should we care about checks and balances on power?
You'd have to have control of a large amount of devices via virus infections. This is typically called a bot net and is hard to do / probably illegal based on where you are.
No problem. Glad it worked out.
