With
the U.S. leader and his minions increasingly ignoring diplomatic
norms and threatening to invade and takeover not only non NATO
countries to their south as they have at least in part Venezuela
but both Greenland and Canada I tried to find out what
limitations their were upon their moves. Very little it would seem in
both practical terms and as recent actions have made obvious, sure
“congress” supposedly has check and balances but does not even
have to be notified until 2 days after he has already started one!

A “wartime president” is a
descriptive term, not a formal title, for a U.S. President leading
the nation during significant armed conflict.

Constitutional Authority and Expanded
Powers

A president’s wartime role stems from
the Commander-in-Chief clause in Article II, Section 2, Clause 1 of
the U.S. Constitution. This clause designates the President as the
“Commander in Chief of the Army and Navy of the United States, and
of the Militia of the several States, when called into the actual
Service of the United States.” This grants the President broad
powers to direct military operations, deploy troops, and formulate
combat strategies.

This role allows for expanded
presidential powers during conflict, enabling the issuance of
executive orders related to national security. These orders can
mobilize resources, direct industries towards war production, and
establish new agencies to manage the war effort…………….

Checks and Balances on Wartime
Presidential Power

The U.S. system of checks and balances
limits presidential power, even during wartime. Congress holds the
constitutional power to declare war, raise and support armies, and
provide for a navy. This legislative authority checks the executive’s
ability to unilaterally commit the nation to prolonged conflict.

The War Powers Resolution of 1973
defines the balance, requiring the President to notify Congress
within 48 hours of committing armed forces to military action and
limiting deployments to 60 days without congressional authorization.

Seems to me that unless congress
gets it act in gear and puts the brakes on this regime that we are
all, world wide, in for a rough ride, and even if they do act will
it even then stop this power hungry bunch of autocrats.
