"The United States and our international partners made major strides to defeat and degrade international terrorist organizations in 2017. [...] Despite our successes, the terrorist landscape grew more complex in 2017. [...] In 2017, the United States led efforts to enhance the international community's law enforcement and other civilian capabilities that are increasingly essential in the next phase of global counterterrorism. [...] In addition, throughout 2017, the State Department led bilateral diplomatic efforts with key countries to improve border and aviation security and information sharing. [...] 'Country Reports on Terrorism 2017' provides a [...] detailed review of last year's successes and challenges so we can consider how to strengthen our counterterrorism efforts going forward. As we look to the rest of 2018 and beyond, the United States remains committed to working with our allies and partners to confront the shared threat of global terrorism."
