Harlan Ullman writes an open letter to Donald Trump demanding clarification on Trump's opposition to the Joint Comprehensive Plan of Action.

If successfully implemented, the JCPOA will ensure Iran does not become a nuclear weapons state for the next decade and a half and presumably for much longer. Congress will reject this agreement with some Democrats joining all the Republican members in dissent. The threshold number of votes needed for the administration to sustain a presidential veto is 34 in the Senate or 146 in the House.

Suppose golf followed politics? Fair play would fall victim to foul play. Rules would count less. And the values that have made and will continue to make golf great would be twisted from doing one's best to doing whatever it takes to win.

Washington may claim that it did not intended to subsidize Iranian support for terrorism or an increase of repression, suffering and abuse in Cuba, but those consequences are real and Raul Castro in Havana and the Ayatollahs in Iran have been emboldened.

WASHINGTON, Aug. 18 (UPI) -- Donald Trump's plan to finance a border wall by withholding remittances may not be a campaign promise, but rather a means to obtain the presidency.

A thermonuclear war thankfully was never fought. And, as remote is the specter of a Sanders versus Trump race. Unthinkable -- one hopes.

If Republicans are truly serious about winning the White House, they need to come to their electoral senses.

BRUSSELS, Aug. 5 (UPI) -- Struan Stevenson: Iran's Supreme Leader has already breached a key clause in the pact. This pact should be rejected. The only way to make the world a safer place is to topple the corrupt mullahs and restore freedom and democracy to the beleaguered people of Iran.

When George W. Bush made the decision to launch Operation Iraqi Freedom to topple Saddam Hussein in 2003, his administration failed to answer the simple but crucial question of "what next?" As the Obama administration launches its campaign to protect the nuclear deal with Iran ratified within the Joint Comprehensive Plan of Action, the White House cannot repeat the same fatal error of its predecessor.

The EU's High Representative for Foreign Affairs, Ms Federica Mogherini, plans to travel to Tehran on Tuesday to open a new dialogue on "bilateral issues" with Iranian officials a fortnight after the nuclear deal between Iran and the world powers. Yet her trip puts in peril Europe's democratic values.

If Trump were really committed to winning the Oval Office and was prepared to put his money where his ever-present mouth is, he would be a serious candidate.

A new naval rivalry is developing in South Asia between India and China

Make no mistake: the intense debate and negotiations over the P-5 plus One nuclear agreement with Iran are just beginning. However difficult the talks in Switzerland and Austria over the past four years may have been, the coming months will make that pothole filled road look like a modern eight-lane super highway. Certain members of Congress abetted by the Israeli government and its American supporters will do their level best to kill the Joint Comprehensive Plan of Action (JCPOA).

MAD now should be redefined properly to mean Mutual Assured Disruption as it applies to societies, individuals and standards of living.

WASHINGTON, July 6 (UPI) -- When he entered office, did anyone think that Nixon would go to China and to the Soviet Union three years later? Barack Obama is not Richard Nixon. But that does not mean opportunities do not exist if we are clever, innovative and inventive enough to consider them.

Tomorrow I shall be addressing the Royal United Services Institute's Land Warfare conference with "An Effective Brains Based Strategy for the 21st Century."

BRUSSELS, June 28 (UPI) -- With the end-of-June deadline for a nuclear agreement with Iran fast approaching, prominent political and government leaders, past and present, from around the world are stepping up calls to beware of making concessions that would embolden the mullahs in Tehran and further destabilize the already shaky Middle East.

BRUSSELS, June 24 (UPI) -- There is increasing frustration that President Obama seems to be committing to too many concessions and weakening the West's approach to the Iranian regime.

Jeb Bush and Hillary Clinton have now formally entered the presidential 2016 sweepstakes, joining a small platoon -- if not battalion -- of contenders on both sides of the aisle that likely will grow.

2015 is indeed an event filled year that could help put some of the "great" back into Great Britain.
