The diagnosis and management of tension pneumothorax.

While technically the President cannot declare war without Congress, under the War Powers Resolution of 1973, the President can send troops into combat as long as he informs Câ¦ongress within 48 hours of doing so .

Pre-emptive strikes and undeclared offensive military expeditions are not powers delegated to the executive branch in the Constitution, and are, therefore, unlawful. Thomas Jefferson stated this quite eloquently when, in 1801, he said that, as President, he was âunauthorized by the Constitution, without the sanction of Congress, to go beyond the line of defense.â
