Why has the U.S. increased military help to Japan, and why are they going to pull out in mid-April?

The United States has continued to increase military help to Japan (Operation Tomodachi), to help deal with the disasters of 11 March.

Recently the USMC said it was sending a team specially trained in nuclear emergencies, and, the U.S. military is conducting a massive three day search for missing people in Japan, along with Japanese Self Defense Forces.

On top of that there are reports that the U.S. military is going to pull out most forces in Japan in mid-April.  The source of this info was not named.  It is thought some U.S. personnel will remain to help deal with the nuclear disaster.

It’s not just military personnel that the U.S. has sent, but personnel from other government agencies, as well as tons of equipment including radiation protected robots from the INL in Idaho. All this at taxpayer expense.

I know many experts, at the beginning of this Fukushima Daiichi disaster, said it wasn’t that bad, and rated it on par with Three Mile Island.  Those experts who called it another Chernobyl were dismissed by officials.  If that’s so, then why so much personnel and equipment from the United States?  And why, apparently, a pull out by mid-April?

Is there a reason 18,000 Japanese, and 7,000 U.S., troops will under take a massive, intensive search for missing people this weekend, then call it good after three days?  The official reason is that it will coincide with low tide along the coastline. The search will not take place in the radiation danger zone.

There’s a lot of evidence that the nuclear disaster is much worse than is being officially reported. For one, TEPCo has been caught lying about it’s radiation readings, twice now. Also, the IAEA, along with Greenpeace, has given their radiation readings which are much higher than what the government is issuing. The International Atomic Energy Agency has even asked for expanded mandatory evacuations, which the Japanese government said no to.

The problem for the United States is that the prevailing winds from Japan bring the radiation contamination right to it. The winds blow towards the U.S. from Japan.

So it is very likely that this nuclear disaster is worse than what is publicly stated, and, the United States is right in the path of any toxic wind from Japan.  Is this why the U.S. is sending so much help to Japan?

Why would U.S. forces begin ending their Operation Tomodachi in mid-April? Is it because only so much can be done to suppress a major disaster (like full melt down), and after that you need to get the hell outa Dodge? There is a time factor when dealing with nuclear disasters, and several experts stated it was time to start dumping concrete last week!
