Excerpts of the President's News Conference
... I might restate too the well-known and what I hope is becoming the historic attitude of our Government, of desiring to do everything that we can, without jeopardizing our own interests, to help the European situation. We have realized all along that it would be useless to have any thought over there that there must be a constant reliance on us. I think I have stated in some of my addresses that we couldn't help people very much until they showed a disposition to help themselves. I think that disposition is becoming more and more apparent abroad every day, and it is a rising of a condition that is ex-ceedingly gratifying to those that want to help and those that want to see the European situation progressively developed.
