Amid Soaring Tensions, Leaders Prepare for Key Global Security Summit Henry Ridgwell MUNICH, GERMANY - U.S. Secretary of State Mike Pompeo and Pentagon chief Mark Esper will join hundreds of global leaders in Germany Friday for the three-day Munich Security Conference. Numerous security flashpoints around the world, from Syria, Yemen and Iran to Hong Kong, Ukraine and Libya, add to the growing tension and unease ahead of the summit, which takes place against the backdrop of the coronavirus outbreak and a global climate emergency. The United States' large delegation is a sign that the Washington wants to counter accusations that it is disengaging, says analyst Elisabeth Braw of Britain's Royal United Services Institute, who is attending the annual Munich conference. "As we speak actually the U.S. is beginning its largest military exercise in Europe in a quarter of a century," noted Braw in an interview with VOA. "And that's worth remembering when we talk about the U.S. disconnecting or disengaging from Europe." US-Iran tensions Washington's biggest showdown in Munich is likely to be with Iran, which is sending Foreign Minister Mohammed Javad Zarif to the summit. He and several other world leaders and government ministers will be given around 15 minutes to address the conference, before question and answer sessions. Several bilateral meetings usually take place on the sidelines of the conference, which is seen as a key annual event to sustain dialogue between global strategic rivals. The U.S. killed top Iranian General Qassem Soleimani in a drone strike earlier this year. Retaliatory air strikes by Iran on U.S. bases culminated in the accidental shooting down of a Ukrainian Airlines passenger jet, killing all 176 people on board. Conference host, former German Ambassador Wolfgang Ischinger, hopes the conference will offer a lifeline for the Iran nuclear deal that the U.S. withdrew from, with Europe at the forefront of negotiations. .
