Getting close to 2k tanks. If only the Ukraine had set a better trap for the Russians. What’s worrisome is that the tanks may be necessary against the Chicoms. The weapon appears obsolete with the easy ability to take them out.
If there were only a few submarines patrolling around Hawaii just before Pearl Harbor was attacked.
The tank is not obsolete. If used with proper tactics it can still be a war winner.
US submarines around Hawaii would have been almost useless. US torpedoes were nearly worthless at the time. Its possible that a US submarine patrol line could have spotted the Japanese fleet, but thats unlikely. Subs have poor surface vision.
What would have helped, some, would have been a much higher rate of air patrols around Hawaii; these would have been much more likely to spot the Japanese fleet than submarines. And there were plenty of long range aircraft in Hawaii.
But everyone in Hawaii was working on a peacetime basis, or nearly so.
