Now THAT is funny!!!!!!!! plus they're know for dikes! 
Fact of the matter is that nobody has a clear solution to stop this leak. It's like a blind guy pissing all over his hand and trying to clean up with the other hand while still pissing only to realise in the end it's still coming out and until the flow stops he'll still have his hand dirty no matter what you do. 
The Dutch never claimed they could plug the hole, they claimed they could help contain the spill. in case you missed this:

Dutch consul slams US foot-dragging on oil spill

Three days after BP’s Deepwater Horizon drilling platform exploded in the Gulf of Mexico, the Netherlands offered to help. Ships could have set about clearing the oil using Dutch sweeping arms, but the US government didn’t take up the offer. Dutch Consul General Geert Visser in Houston told Radio Netherlands Worldwide he was disappointed.
The US response, says Mr Visser: “‘Thanks for your help, but at the moment we can manage ourselves.’ And that was it.” He puts the reticence down to pride.
Late
Weeks later the pride was forgotten and the US came to the Dutch for help after all. “Almost a month later – a month too late, of course – Washington did make a request to send the sweeping arms to Houston in Texas,” says Mr Visser. “They arrived in three 747s, ten days later. They were then transported to Louisiana to be mounted on ships.”
US ships are now fitted with the arms and should be operational within a few days. Each pair of arms can clear around 20,000 tons of oil a day.
Experience
Mr Visser thinks Dutch experience with water management and dyke construction may have played a role in the change in US attitude. “They evidently realised that the Netherlands has superior equipment that can work quickly and efficiently.”
The US also initially turned down another Dutch proposal. The Dutch knowledge institute Deltares and dredging company Van Oord put forward a plan to build a sand dyke stretching for dozens of kilometres within three weeks. And here too, Washington came round in the end.
Jones Act
Not only capricious US decision-making has made life difficult for the Dutch companies, but also protective US legislation. Consul General Geert Visser’s pet hate is the Jones Act: “It means that Dutch ships, or whatever other ships not under a US flag, can’t operate in US waters.” According to the Jones Act, all goods in US waters have to be transported by US ships.
On Wednesday it was announced that oil company BP is increasing its capacity to capture the oil escaping from the leaking well in the Gulf of Mexico. The company has installed a cap over the well. From next week it hopes to increase the containment capacity from around 15,000 barrels a day to 28,000.
