Anakin was at a loss for words. That was the main reason the Jedi lost so many each encounter with the Separatist forces. Individuals failed, certainly, and there were mistakes the Jedi made in strategy and policy that Palpatine didn’t implement; but they shouldn’t have lost so many. They should have been more successful.
They shouldn’t have gone to war. There shouldn’t have been a conflict.
Anakin simply nodded. He couldn’t add anything that would make their hearts lighter, and he didn’t want to make them heavier.
