If the US were to enforce a no-fly zone it could be drawn into a direct confrontation with Russia, which conducts bombing raids over areas controlled by Islamic State terrorists. Though Gabbard, who represents a constituency in Hawaii, is not of Indian descent, she is a second-generation Hindu by religion. She is only 35-years-old and is considered a rising star in the Democratic Party.

“For years, the issue of ending interventionist, regime change warfare has been one of my top priorities,” she said in a veiled attack on Clinton who has promoted an agenda of overthrowing governments from Egypt to Ukraine with disastrous results.

Gabbard made a scathing attack on Republican neo-conservative hawks like Paul Wolfowitz, the planner of the deadly Iraq War, who had crossed over to Clinton’s side. She said it was important for her to meet the “President-elect now before the drumbeats of war that neocons have been beating drag us into an escalation of the war to overthrow the Syrian government - a war which has already cost hundreds of thousands of lives and forced millions of refugees to flee their homes in search of safety for themselves and their families,” Gabbard said.

She has previously expressed support for Russian bombing of Islamic State-held territories in Syria. “While the rules of political expediency would say I should have refused to meet with President-elect Trump, I never have and never will play politics with American and Syrian lives,” she added.

During the Democratic Party’s presidential nomination race Gabbard was aligned with Bernie Sanders, the independent socialist who defied the party leadership to run against Clinton. Gabbard resigned as vice chairwoman of the Democratic National Committee after clashing with the then-Chairwoman Debbie Wasserman Schultz, whom she accused of unfairly backing Clinton and working against Sanders.

This could make her a potential conduit to the discontented supporters of Sanders, who emerged a strong rival to Clinton with his populist platform appealing to the disempowered, the working class and foreign policy doves.

Underlining the differences with Trump on other matters, Gabbard said, “Where I disagree with President-elect Trump on issues, I will not hesitate to express that disagreement.” Gabbard has criticised President Barack Obama for his reluctance to label as Islamic extremism terrorist attacks carried out by some Muslim, a criticism Trump has also voiced. She has advocated a tough line on Pakistan for its role in international terrorism and tried to get Congress to cut aid to Islamabad and increase pressure on it to stop this violence.
