If Britain pledges military support they must take steps to send troops. Otherwise British diplomatic promises are worthless.
Better not to make such a promise then to make a promise and then break it.
Do you think declaring a war on the German invader and then carrying it was not enough on the British side?
Poland's fate after the war was unforeseeable during the September '39 crisis, and was beyond the control Great Britain or any other non-communist ally for that matter.
