NATO on Clinton's orders bombed Serbia, killing Christians to advance the cause of Al Qaeda. It can hardly be taken for granted that everything Poles are doing in their airspace is either NATO related, or for the common good.
Poland, as you folk have well noted, has been nationalistics, and interventionalistic throughout the region and its good to have a check against the gross interventionalism Poland has been exhibiting before they do something crzy like act unilaterally outside of NATO to attack something and cause a war.
