Matthew Waxman: The Constitutional Power to Threaten War
Michael Ramsey

Matthew C. Waxman (Columbia Law School) has posted The Constitutional Power to Threaten War (Yale Law Journal, Vol. 123, 2014, forthcoming) on SSRN.  Here is the abstract:

Existing legal scholarship about constitutional war powers focuses overwhelmingly on the President's power to initiate military operations abroad and the extent to which that power is constrained by Congress. It ignores the allocation of legal power to threaten military force or war, even though threats – to coerce or deter enemies and to reassure allies – is one of the most important ways in which the United States government wields its military might. This paper fills that scholarly void, and draws on recent political science and historical scholarship to construct a richer and more accurate account of the modern presidency's powers to shape American security policy and strategy.

As a descriptive matter, the swelling scope of the president’s practice in wielding threatened force largely tracks the standard historical narrative of war powers shifting from Congress to the President. Indeed, adding threats of force to that story might suggest that this shift in powers of war and peace has been even more dramatic than usually supposed, at least in terms of how formal congressional checks are exercised. This paper shows, however, that congressional checks and influence – even if not formal legislative powers – operate more robustly and in different ways to shape strategic decision-making than usually supposed in legal debates about war powers, and that these checks and influence can enhance the potency of threatened force.

As a prescriptive matter, this paper also shows that examination of threatened force and the credibility requirements for its effectiveness calls into question many orthodoxies of the policy advantages and risks attendant to various allocations of legal war powers, including the existing one and proposed reforms. Instead of proposing a policy-optimal solution, this paper concludes that the allocation of constitutional war powers is – and should be – geo-politically and strategically contingent; the actual and effective balance between presidential and congressional powers over war and peace in practice necessarily depends on fundamental assumptions and shifting policy choices about how best to secure U.S. interests against potential threats.

It's an great constitutional question, and my textualist/originalist answer is this: 

The President has the power to threaten war, so long as the threats are just threats and do not rise to the level of an actual declaration of war.  The power is part of the President's executive diplomatic power (from Article II, Section 1), which gives the President the power to communicate with other nations on behalf of the United States.  Those communications can be friendly or unfriendly, threatening or non-threatening, on whatever subject the President chooses.  True, the President cannot (in my opinion) constitutionally deliver on a threat of war, since the declare war clause gives that power to Congress.  But the declare war clause does not limit the President's ability to talk about war, any more than Congress' power to regulate foreign commerce limits the President's ability to talk about trade sanctions.  The President can threaten a trade war, and he can threaten a real war.

(Note: I am ignoring here the issue of the U.N. Charter, which does (textually) limit the nation's ability to threaten war and which the President is arguably bound to faithfully execute).
