Translation of "recklessly" into Chinese

The United States and the south Korean authorities should no longer behave recklessly, daring talk about “provocation” and “threat” from someone.

美国和南朝鲜当局不应草率行事,肆意谈论别人的“挑衅”和“威胁”。

It is true, but unhelpful, to say that governments have only themselves to blame for having recklessly rushed into this wild ride.

说让政府鲁莽地加入这场狂欢的唯一罪魁是政府本身,这固然正确,但无济于事。
