Re: "call to action", part of Heidegger's project by my read is to interrogate such phrases. I think he would refute that "action" is what we need and that orienting ourselves towards the world in terms of "action" is obscuring the Question of Being. He himself offers no real way out. In his posthumously published Der Spiegel interview [2] he himself says "only a God can save us".
I assume you're making a snide reference to his involvement with Nazism, which I'm not going to attempt to downplay or respond to here. He himself in his later life, however, went and lived a humble life in the Black Forest. Can or should we all "return to the land"? No. But his writing certainly has expanded my view of the world and my "image of thought". He is a worthwhile study.
How to Read Heidegger [3] is a great primer for any who may be interested.
