It has been one month since US President Donald Trump returned to the White House. In that time, he has signed executive orders at a faster pace than in his first term and said things that have shocked the world. Experts say there is a strategy behind this flurry of activity.



Since his return to office, Trump has launched various initiatives that include leaving the Paris Agreement and imposing tariffs.



Assessing his performance, he said, "We've accomplished more in four weeks than most administrations accomplish in four years."



Trump's way of communicating with the public varies among news conferences, comments from Air Force One, and posts on social media.



The strategy is called "flood the zone." Trump reportedly uses it to drown out criticism, including that from the media.



His former chief strategist Steve Bannon is said to have played a key role in applying the strategy during Trump's first term. Bannon said the media can focus on only one thing at a time, because they are dumb and lazy.



Sophia University Professor Maeshima Kazuhiro said the administration has launched a huge number of initiatives, but that so far it is difficult to tell whether they are successful. He added that Trump's momentum looks set to continue for around two months but may then gradually wane.



An opinion poll this month showed Trump's approval rating at 45 percent -- the same as shortly after his inauguration last month.
