He spoke with full confidence, but Gao Guang could never say it's impossible, that we can't wait until the afternoon and need to slip away now.
So we must continue to stand guard, but we have to play it by ear. If there really is a major attack and it's truly unstoppable, running away is running away, surrendering is surrendering. After all, PMC Company carries out legitimate business and signs formal contracts. There is a clause in the contract that allows for abandonment in the face of force majeure.
But how to determine what constitutes force majeure is up to PMC Company's professional ethics.
For someone like Andrew, any attack would count as force majeure, and that's definitely not okay. So Gao Guang figured they'd have to put up a fight no matter what, but didn't have to be overly persistent. As soon as they saw that the enemy's strength was indeed overwhelming, they would have to invoke the force majeure clause.
