'Most Logistically Challenging Event' U.S. Has Ever Seen'
This is the leader of FEMA spewing this nonsense about a 100 x 30 mile island.
The Pacific theatre in WWII and the Berlin Airlift comes to mind.
Seems like all Trumpers do is make excuses.

In a matter of weeks the Allies had turned the beaches of Normandy into a major port.
That would be moving the goalposts, as the quote in the OP never implied a measure or quotient of years necessary for success, only that it is "the most logistically challenging event the US has ever seen".
Were that measure actually relevant though, bear in mind the the Berlin Airlift began six days after the blockade had begun. 
When a new administration comes in a wrecks the existing system that has thousands of highly qualified and experienced personnel, you're probably going to fail miserably - at least in the first year or two. And, if you don't replace them with equally qualified and experienced personnel, you will continue to fuck up.
As any experienced first-responder or military commander will tell you, a rapid efficient response to any emergency or crisis requires not only a lot of materials and equipment, but training, training and training and practice, practice and practice, AS A TEAM.
Team work starts at the top. Need I say more?
