“The first 100 days is Biden and the Democrats’ declaration of war on small business,” said Alfredo Ortiz, president of the Job Creators Network. Although Mr. Biden did impose sanctions on dozens of Russians over cyberattacks and election interference, some analysts say, the president’s foreign policy on China and other challenges has been sidelined by his focus on the pandemic and domestic spending increases. A senior administration official told reporters this week that some of Mr. Biden’s work on national security and foreign policy isn’t “splashy” but added that the change from the Trump administration is no less important.
