Indian-American Republican presidential candidate Nikki Haley slammed her ex-boss Donald Trump and 2024 rival Ron DeSantis over their refusal to state outright whether they want Ukraine to win its war against Russia.
In recent town hall events, Trump, the favorite for the Republican presidential nomination, said that he wanted the war to end, but that he would help Ukraine and Russia negotiate a settlement.
Florida Governor DeSantis, Donald Trump's nearest rival for the Republican nomination, said recently that he supports a settlement to the war, and that he hopes fighting will end by the time the next President takes the oath of office in January 2025.
Haley, the only woman in the race for the Republican nomination, lambasted DeSantis for saying this year that Ukraine was a "territorial dispute", a comment that drew widespread criticism and that he has since walked back.
"For them to sit there and say that this is a territorial dispute - that's just not the case, or to say that we should stay neutral," Haley told voters in the early nominating state of Iowa during a televised CNN town hall event.
"It's in the best interest of our national security for Ukraine to win," she added.
Ukraine is an issue that divides Republicans, because of an isolationist streak among many of the party's primary voters.
Haley, 51, a former South Carolina governor, declared her White House bid in February but finds herself in a crowded Republican field that will reach double digits this week with the entrance of more contenders, including former Vice President Mike Pence.
Trump dominates the field among potential Republican primary voters with 49 per cent support. DeSantis is next with 19 per cent. Haley has just 4 per cent support, according to the latest Reuters/Ipsos opinion poll conducted in May.
Haley and many of her rivals polling in single digits are trying to differentiate themselves from DeSantis, in the hope that he stumbles and they can become the main alternative to Trump.
But some have also begun to criticise Trump himself, after months of shrinking away from attacking the former President out of a fear of alienating his hardcore supporters.
She also attacked Trump for congratulating North Korean leader Kim Jong Un last week after the country was elected to the executive board of the World Health Organisation.
