At least, Chemberlain was in a position to go to war against Germany if he wanted to, although he knew well that it wouldn't be easy or advantageous to Britain, so he had good reasons to try to avoid the inevitable.
As I understand it, Chamberlain did what he could, or more precisely: he didn't do what he couldn't. The shameful part of the Munich agreement was that he entered into a treatise that sanctioned the German occupation of territory belonging to a third nation. That the agreement would prove to be worth less than the paper it was written on he might have guessed, but couldn't know.
That's my understanding of it. The Dutch government (and parliament) are currently awaiting the results of investigation of the exact cause of the MH17 crash. It's difficult to predict what the government will do should it become apparent that Russia did indeed play a part in it. Obviously the government doesn't look kindly on killing 196 Dutch citizens, but I expect they'll try to find redress through legal means. The Netherlands do have considerable trade with Russia. Considering the relative sizes of their economies, sanctions will probably hurt the Dutch more than the Russians.
