WASHINGTON — President François Hollande’s administration expressed Monday the French president’s deep appreciation for President Barack Obama’s strong statement and actions ever since the attacks of last Wednesday, according to a senior official in Hollande’s office.

The official said Obama was “very present” from the start. He was one of the first leaders to call Hollande on Wednesday, and then made several strong public statements.

All French, especially Hollande greatly appreciated Obama’s “exceptional visit to the French Embassy in Washington.”For us It was an emotional moment of solidarity,” the official said.

U.S. Secretary of State John Kerry defended the Obama administration against criticism for not having a high level official attend a unity march in Paris and said he will head to France on Thursday.

Kerry called the criticism “quibbling” when asked about the absence at the anti-terrorism rally Sunday. At least 3.7 million people attended the event — including 40 world leaders — in a show of solidarity against the terror attacks in France over the past week.

“The U.S. has been deeply engaged with the people of France since this incident occurred,” Kerry told reporters, adding that the United States has offered intelligence and law enforcement help.

“This is sort of quibbling a little bit in the sense that our assistant Secretary of State Victoria Nuland was there and marched, our ambassador was there and marched, many people from the embassy were there and marched.”

Kerry made his comments from India, where he was attending an entrepreneurship summit with new Prime Minister Narendra Modi — with whom the United States is hoping to develop much closer trade ties.

“I’ve been here in India for a prior planned event, would’ve personally very much wanted to have been there (in France) but couldn’t do so because of the commitment that I had here,” Kerry said. “But that is why I am going there on the way home, to make it crystal clear how passionately we feel about the events that have taken place there.”

Kerry expects to leave on Thursday and arrive in France on Friday.

Attorney General Eric Holder was in Paris attending a security summit on combating terrorism. He recorded interviews that appeared on several U.S. news outlets Sunday, but was not spotted at the unity march.

On Sunday night, a White House official who asked not to be named added: “It is worth noting that the security requirements for both the President and (Vice President) can be distracting from events like this – for once this event is not about us!” The official did not address how other prominent world leaders were able to work around the security requirements.

Who did go

British Prime Minister David Cameron, German Chancellor Angela Merkel, Israeli Prime Minister Benjamin Netanyahu, Palestinian Authority President Mahmoud Abbas and Russian Foreign Minister Sergey Lavrov were among those who attended, along with religious leaders.

Fareed Zakaria, hos of CNN’s “Global Public Square,” called the absence of top U.S. officials a mistake.

France is the United States’ “deepest ideological ally,” he said, and it would have been a meaningful image to have a senior administration member, or the President, standing shoulder to shoulder with other leaders.

Zakaria noted that security concerns didn’t dissuade Netanyahu or Abbas or other leaders from showing up. But Obama’s absence did show that the struggle against radical Islam is “not all about America,” Zakaria said.

“Many people have tended to think that Islamic terrorism wouldn’t exist without America,” Zakaria said. “This is really a struggle between the civilized world and a band of extremists. Even if you take the U.S. out of it … the civilized world is up in arms.”

What Obama said

Obama spoke about the Paris attacks on Friday, saying he wants the people of France to know the United States “stands with you today, stands with you tomorrow.”

The White House also announced Sunday that it will host a February 18 summit aimed at countering violent extremism.

White House Press Secretary Josh Earnest said that event will “highlight domestic and international efforts to prevent violent extremists and their supporters from radicalizing, recruiting or inspiring individuals or groups in the United States and abroad to commit acts of violence, efforts made even more imperative in light of recent, tragic attacks in Ottawa, Sydney and Paris.”

He said the summit will include presentations, panel discussions and small group meetings, focused on the local, state and federal government levels.
