Resistance from a few, whose own claims to being major Powers are becoming increasingly unpersuasive, should not be allowed to stand in the way of change.

Finally, and interestingly (if unpersuasive to many), all of Iran s leaders continue to insist that weapons of mass destruction are incompatible with the basic tenets of Islam.

But this is unpersuasive the siloviki have not coalesced into a coherent group and consolidated their authority at least so far. They lack a leader, have no agenda, and failed to seize power during Putin's first term.

We should not allow any unpersuasive claims by some major Powers and others to stand in the way of timely and necessary change, change that would make the Security Council more representative, effective, transparent, democratic and accountable.
