		<description>Barton, I stated in my post that I believe in the right of the Jews to have a homeland, and for the record, I do not agree with Steve&#039;s comment about evacuating all Jews out of Israel and moving to  them to New York.  That idea makes no sense whatsoever.  I also make it clear that I believe the Palestinians have a right to a homeland.

I live in Canada, a much smaller country, population-wise than the US.  I wouldn&#039;t like it very much if the US came into my country, expanded her borders, and threw me out of my home, forcing me to live somewhere I have no desire to live.  I would most likely, take up arms, and fight back for what I believe is mine.

Neither would the people of Montana like it if Canada, with it&#039;s much superior military technology, (we supply our troops with Mukluks - I can&#039;t tell you what they are, it&#039;s a closely guarded government secret) invaded their state.  (We love their open roads and lack of speed limits.)  Then the much superior Canadian invasion force displaced it&#039;s citizens.  The reaction would be much the same.</description>

Neither do I.

[[&lt;i&gt; Why are you so quick to judge Steve because he happened to state, what quite frankly, many people are thinking.&lt;/i&gt;]]

Because he wants Israel forcibly evacuated to New York and all American Jews moved there and presumably the border sealed off.  Did you not read his post?  Go back and read it again.  It&#039;s essentually identical to David Duke&#039;s plan for settling blacks in &quot;Minoria,&quot; Hispanics in Bantustans in the west, Jews in the northeast, etc. -- leaving 98% for the Aryans, of course.

[[&lt;i&gt; No we are not all racists. I happen to think the Jews have a right to a homeland. But, so do the Palestinians. &lt;/i&gt;]]

I agree.</description>

		<description>Barton, not everyone has to have the opinion that Israel is a favored nation above all others.  Why are you so quick to judge Steve because he happened to state, what quite frankly, many people are thinking.  No we are not all racists.  I happen to think the Jews have a right to a homeland.  But, so do the Palestinians.  I also believe, that America, or any other nation should not have to do the dirty work of any other nation.  Let her fight her own wars.  If Israel is concerned about Iran, let Israel take care of Iran.  Why should thousands more US soldiers be slaughtered fighting someone else&#039;s battle.  No, the Jews should not have to evacuate Israel, but they should have to find a way of co-existing with her neighbours, and like it or not, that includes the Palestinians.  Rabid fundamentalists and Christian Zionists like John Hagee, quite frankly scare the crap out of me far more than a Tunguska event.  These people are driven by a fanaticism that borders on insanity.  The attitude seems to be, &quot;If Israel cries &#039;Foul&#039;, we will come running.&quot;  They view it as their divine mandate to protect this nation at all costs, yet thousands are dying in Darfur.  They are determined to bring about nuclear annihilation to fulfill some type of biblical end time prophecy (lie).

I apologize if this offends anyone, especially any Jewish people that may be here, I reiterate, I am not opposed to the Jews having a homeland.  Personally I think many Jews agree that it is time to find a solution to this never ending quagmire.

Anyway, back to the topic at hand.  Mick stated that these events should be more common.  Let&#039;s not forget that 75% of the Earth&#039;s surface is covered by water.  It is only in the last 50 or so years that we would have been able to detect airbursts over our vast oceans.  So, that being said, these events could very well be more prevalent than we think.  We were just unable to see them.  Such a possible event took place over the Indian Ocean in the late &#039;70&#039;s, where the Vela satellite observed a flash over the Southern Indian Ocean.  This is widely believed to have been either a South African, or Israeli nuclear test, but has never been confirmed.</description>

		<description>The absence of strikes by smaller objects may be due to their being more prone to be deflected by the atmosphere, or to burn up in it.  The impact cross-section at Earth&#039;s surface won&#039;t resemble that at the Moon&#039;s surface.</description>

		<description>StevoR posts:

[[&lt;i&gt;Here’s a simple idea America needs to adopt - Leave other nations the heck alone &amp; stop funding Israeli aggression in a region where its never wanted &amp; will never fit. Evacuate Israel &amp; let the Jewish lobby purchase New York and surrounds at crippling cost.&lt;/i&gt;]]

Yeah, that&#039;ll show those dirty Jews!  Good plan, Stevo.

Um, wait, it&#039;s a ridiculous, racist plan better suited to the fantasies of William Turner and David Duke than to a science blog.  My bad.

[[&lt;i&gt; Give Palestine back to the Palestineans, leave the rest of the planet in peace -and we’ll all be incomparably better off! &lt;/i&gt;]]

Like we were when we took that attitude in the &#039;20s and &#039;30s.  Just leave other countries alone, and things will be fine!  It&#039;s the US that causes all the problems!  People in other countries are sinless!

Oh, wait, that&#039;s stupid.</description>

		<description>Glad to see they were able to use all those warhead re-entry simulations for something.  Gotta admit, the simulations are beautiful.  Any idea how much CPU time it takes to run something like that?


Charles--there actually aren&#039;t that many 3.5 megaton devices around anymore.  The multi-megaton monsters were part cold-war pissing match, part designed to distroy hardened silos when ICBM accuracy was measured in miles.  Once ICBMs actually got able to hit things, weapon sizes dropped dramatically. Most of the U.S. arsenal is in the 100KT range, and only the highest yield weapon in the inventory is 1.2Mt.

Not that that makes them any more pleasant...
