Since when did the United States abandoned its traditional world leadership role, especially at a time when just this past week, the president of china says, okay, we're going to adopt a cap and trade program and we're reducing our CO two emissions and we want to create jobs in solar and wind and efficiency.
從什麼時候開始,美國放棄了其傳統的世界上司角色,特別是在剛剛過去的一週,中國總統說,好吧,我們將採取一個上限和交易計劃,我們正在減少我們的二氧化碳排放量,我們希望在太陽能和風能以及效率方面創造就業機會。
