I have no mod point but if somebody can, please mod this up. Writing that the MEK is an assassination arm of the Mossad is just repeating Iranian government propaganda. They are a Marxist movement that was fighting the Shah before the revolution and has been forced into exile by the islamists after the revolution. As one of the political opponent of the islamist government in Iran, they may have received support from countries opposing the iranian government (although I am not aware that they ever received specific help from Israel). But they are certainly not affiliated to Mossad.

They have sponsored violent actions in the past, but they are not considered a terrorist movement in Europe anymore ( although they still are in the US)

Well, the thing is that the smaller european countries have much less space to spare. US is basically an empty land by european standard, so it's much easier to accomodate a big number of immigrants coming in.

To give a sense of scale, Germany has about 8 times the population density of the US. To put it in a different way: if the US had the same population density as Germany, there would be around 2.5 billions US citizens (twice as much as Chinese!).

There are of course other reasons (cultural, political and economical) for the different immigration policies; but your comment about the fact that a country the size of Iowa should not care about immigration seems paradoxical to me....

Although you have been moded as interesting, I believe you are both wrong and a bit arrogant in your reasoning.

Wrong:

If A and B have the same inertial mass, they will accelerate at the same speed, since the gravitational pull they exert on each other is actually the same (action=reaction, remember?). On the other hand, if A and B had different inertial mass (with identical or different gravitational mass), then the one with the lowest inertial mass would accelerate faster.

Arogant:

Finding an explanation to why the inertial mass is equal to the gravitational mass has been one of the guiding goal of the elaboration of general relativity (see [[http://en.wikipedia.org/wiki/Mass#Equivalence_of_inertial_and_gravitational_masses]]) . And you are claiming you can explain this equivalence by a simple thought experiment using just classical principles.

Also, it might even be considered a case of cyclic reasoning: after all, if inertial-gravitational mass equivalence doesn't hold, it might be possible that the principle of conservation of momentum doesn't hold either .
