What did Churchill mean when he said that instead of being forced to snatch his victuals the table Hitler had them serve him course by course?

丘吉尔这句话的意思是，希特勒原本需要通过侵略和掠夺来获取资源（被比喻为“snatching his victuals from the table”，即从餐桌上抓取食物），但最终，由于战争形势的发展和盟军的帮助，希特勒反而得到了资源的供应，就像是被端上一道道菜（“serve him course by course”），这反映了希特勒在战争中所处的被动局面。
