The WTO cannot live up to its name as long as it doesn't include a country that is home to one fift

问题描述:

The WTO cannot live up to its name as long as it doesn't include a country that is home to one fift
汉语意思是什么?换成连词if 意思一样吗

如果 WTO 不能让一个占世界五分之一人口的大国加入,那它就不是名副其实的“世界贸易组织”了.
(这句话应该是中国申请入世的那段时间出现的,home to one fifth, 就是中国了.)
as long as = if可以换成if
