diplomatic powers new extension, now without consulting Congress, now
with Congress's approval; and when at last we entered World War II, he
endowed the precedents of both the War between the States and of World
War I with unprecedented scope.[56]

It is timely therefore to inquire whether American Constitutional Law
today affords the Court a dependable weapon with which to combat
effectively contemporary enlarged conceptions of presidential power.
Pertinent in this connection is the aforementioned recent action of the
Court in Youngstown _v._ Sawyer disallowing presidential seizure of the
steel industry. The net result of that Case is distinctly favorable to
presidential pretensions, in two respects: First, because of the failure
of the Court to traverse the President's finding of facts allegedly
justifying his action, an omission in accord with the doctrine of
Political Questions; secondly, the evident endorsement by a majority of
the Court of the doctrine that, as stated in Justice Clark's opinion:
"The Constitution does grant to the President extensive authority in
times of grave and imperative national emergency".[57] That the Court
would have sustained, as against the President's action, a clear-cut
manifestation of congressional action to the contrary is, on the other
hand, unquestionable. In short, if we are today looking for a check upon
the development of executive emergency government, our best reliance is
upon the powers of Congress, which can always supply needed gaps in its
legislation. The Court can only say "no", and there is no guarantee that
in the public interest it would wish to assume this responsibility.
