US President Donald Trump has begun 2018 where he left off. Since the first of the year, he has attacked a variety of countries in Twitter posts, urging protesters to overthrow the Iranian government, threatening to blow up North Korea and calling for cuts in aid to the Palestinians.

Two things stand out about the foreign policy messages Trump has posted on Twitter since taking office: How far they veer from the traditional ways American presidents express themselves, let alone handle diplomacy. And how rarely Trump has followed through on his words.

Indeed, nearly a year after he entered the White House, the rest of the world is trying to figure out whether Trump is more mouth than fist, more paper tiger than the real thing.

Countries are unsure whether to take his words as policy pronouncements, or whether they can be safely ignored. If Trump's threats are seen as hollow, what does that do to American credibility?

In a series of Twitter posts on Saturday, Trump reacted to questions about his mental fitness by calling himself a "very stable genius."

Even if there is a recognition that Trump's tweets may be largely intended to let off steam or reassure his domestic base, there is an increasing sense that the credibility of the administration, and the presidency itself, is being eroded.

However, Richard N. Haass, president of the Council on Foreign Relations in New York, said the words of the US president matter, he added in a Twitter message: "That is why so many of this president's tweets alarm. The issue is not just questionable policy on occasion but questionable judgment and discipline."

The bottom line, Haass said, is that Twitter posts should be handled as seriously as any other White House statement, lest the currency of what the president says comes to be devalued.

But the Twitter posts have already devalued the president's words, argues R. Nicholas Burns, a former career diplomat and ambassador to NATO.

"Even when Mr. Trump is right, ... there's always some excess or some objectionable statement that undermines American credibility, and it's hard to win that back," he said. "Allies and opponents invest in your judgment and common sense."

He pointed to Trump's decision to move the US Embassy from Tel Aviv to al-Quds [Jerusalem], however delayed or symbolic. That broke with years of international policy consensus, which called for the status of al-Quds to be settled in so-called "peace" talks.

"When you give away the status of Jerusalem [al-Quds] unilaterally and get nothing from ‘Israel' and anger the Palestinians and challenge the world and then you lose, it's a disastrous example of lack of US credibility," Burns said.

The decision infuriated the Palestinians and the Europeans. Then, Trump and his United Nations envoy, Nikki R. Haley, threatened to cut off aid to any country that opposed the new US position in a vote in the General Assembly.

In the end, the vote was a humiliating rebuke of the US, 128 to 9, with 35 abstentions. Most European allies voted against the US, and even European allies in Central Europe, who consider Washington a key guarantor against Russia, did not vote with Washington but abstained.

A senior European diplomat, speaking on condition of anonymity because the person was not authorized to speak publicly, called the al-Quds episode destabilizing and said it had come when the Middle East and the world did not need it.

As much as the Palestinian president, Mahmoud Abbas, has annoyed Trump with his criticism of the al-Quds move, saying that it disqualified Washington from a serious role in any so-called "peace" talks, even the "Israeli" entity has urged Trump to abandon his threat to cut off aid to the United Nations agency that looks after millions of registered Palestinian refugees.

On North Korea, despite Trump's Twitter posts, Pyongyang has gone ahead with tests of intercontinental ballistic missiles and has given no indication that it will agree to denuclearize in exchange for talks with Washington. Instead, it has gone around Washington to reopen talks with Seoul.

Even on Pakistan, where Trump followed through last week on threats to suspend aid over the country's ambiguous support for the American battle against the Taliban, the president was for the Pakistanis before he was against them.

In one of his first calls with a foreign leader after being elected, Trump spoke with the Pakistani Prime Minister, Nawaz Sharif, and gushed that he was a "terrific guy."

"Mr. Trump said that he would love to come to a fantastic country, fantastic place of fantastic people," Sharif's office said in a statement describing the call. "Please convey to the Pakistani people that they are amazing and all Pakistanis I have known are exceptional people."

More recently, Trump switched to threatening them, saying on Twitter that Pakistan had "given us nothing but lies & deceit" and accusing it of providing "safe haven to the terrorists we hunt in Afghanistan."

The public humiliation outraged Islamabad, giving an opening to China, which moved within 24 hours to praise Pakistan's fight against terrorism. Pakistan then agreed to adopt the Chinese currency for transactions, to improve bilateral trade.

François Heisbourg, a French defense and security analyst, commented tersely about Trump's anger this way: "Pushing Pakistan into an exclusive relationship with China."

Trump has been equally changeable with the Chinese, whom the president repeatedly threatened to punish for what he termed trade dumping and currency manipulation, only to say in December that he had "been soft" on Beijing, needing its help on North Korea.

Some suggest that Trump's Twitter posts should not be taken so seriously. Daniel S. Hamilton, a former State Department official who directs the Center for Transatlantic Relations at Johns Hopkins University, said that Trump "uses these tweets and social media to secure his political base," and "whether the tweets turn into a policy or not is a whole different question."

While allies do not necessarily take his Twitter posts as policy pronouncements, they still create significant confusion, said Pierre Vimont, former French ambassador to Washington and former top aide to the European Union foreign policy chief.

Even in areas where allies agree - for example, on the threat posed by North Korea and its leader, Kim Jong-un - "we have a hard time understanding the real policy line from Washington," Mr. Vimont said.
