Ethers are cleaved by acids not by based. Why ?

Description : Ethers are cleaved by acids not by based. Why ? 

Last Answer : The C - O - C bond in ethers like the C - OH bond in alcohols is quite strong. In order to weaken it, the oxygen atom must be protonated. A subsequent nucleophile attack by a strong ... protonation of O atom of ether and therefore only acids can bring about the cleavage of ethers and not bases.
