Donald Trump, America’s previous president,fuelled those concerns with his isolationist rhetoric and his view of alliancesas expensive favours to free-riding foreigners. 《经济学人》上面的一句话。在view作动词时，view sb/sth as sth，此时as sth作宾补。那样，这句话中的as expensive favours是作什么成分？是由介词of引出的宾语补足语吗？
谢谢大咖专家老师们！
Donald Trump,America’s previous president, fuelled those concerns with his isolationistrhetoric and his view of alliances as expensive favours to free-ridingforeigners.
黑体部分是介词短语，作定语修饰 alliances，“作为......的结盟”。假如 view 是动词，那样alliances 则是宾语，asexpensive favours to free-riding foreigners 是宾补，即：He viewedalliances as expensive favours to free-riding foreigners. 是动词 view 接复合宾语结构。
【翻译】美国前总统唐纳德•特朗普（用他）的孤立主义言论与他觉得结盟是对搭便车的外国人的昂贵打折待遇，加剧了这类担心。
