Skeptics about democracy in the 18th and 19th centuries argued that the enfranchised masses would use their votes to seize the property of the relatively few rich. What could be more natural?

Next week, Britain votes in its first general election in five years. Some aspects of its politics will be familiar to Americans. Polls show voters are dissatisfied with politicians of both parties, cynical about whether they will keep their promises and closely divided between two major parties, which have been in existence for more than 100 years.

Two weeks ago, Ted Cruz announced his candidacy for president at Liberty University, and last week, Rand Paul announced at the Galt House hotel in Louisville, Kentucky. Marco Rubio is expected to announce this week at the Freedom Tower in Miami. Others will follow.

Is the tide turning against President Obama's purported nuclear weapons deal with Iran? One sign that the answer is yes is the devastating opinion article in Wednesday's Wall Street Journal by former Secretaries of State Henry Kissinger and George Shultz.

There are still nearly two years left in Barack Obama's presidency, but historians looking back on his record in foreign policy will surely identify one costly error: his refusal to follow through on the implied threat in stating that the Syrian regime's use of chemical weapons would be a "red line."

In her brief press conference at the United Nations, Hillary Clinton led off with a denunciation of the letter to Iranian leaders signed by 47 of the 54 Republican senators. This was in line with Democratic talking points -- a sign that the former secretary of state was, perhaps a bit nervously, taking care to curry favor with the Obama administration.

On Wednesday the Supreme Court heard oral arguments in King v. Burwell, the case challenging the IRS's decision to pay subsidies to lower-income health insurance buyers in states with federal insurance exchanges -- even though the Obamacare legislation authorizes subsidies only in states with exchanges "established by the state."

If anyone had any doubts that most members of Congress oppose the Obama administration's proposed nuclear deal with Iran, they can put them aside after viewing the response to Israeli Prime Minister Benjamin Netanyahu's speech before Congress Tuesday.

"Americans are from Mars and Europeans are from Venus," wrote Robert Kagan in "Of Paradise and Power," published in 2003, just as the United States went into Iraq. Americans, he wrote, see themselves in "an anarchic Hobbesian world," where security and a liberal order depend on military might, while Europe is "moving beyond power into a self-contained world of laws and rules and transnational negotiation and co-operation."

In reflecting on relations between the United States and China, Henry Kissinger in his 2011 book, "On China," notes that since he and Richard Nixon ventured to Beijing more than 40 years ago, "Eight American presidents and four generations of Chinese leaders have managed this delicate relationship in an astonishingly consistent manner, considering the difference in starting points."
