Yet a mechanism of this kind can only work if a third party (the US, the “US plus,” or the Middle East Quartet) is available to monitor the agreement. Otherwise, disputes about fulfillment of this or that provision will lead the entire process back into the familiar quicksand of Middle East futility.
但是，此类机制只有在第三方(美国，“美国加”或者中东四方)可以监督协议的情况下才会奏效。否则，有关落实这条或者那条条款的争议将会导致整个进程回到人们所熟悉的中东无果而终的流沙之中。
