    China's 294 megatons of thermonuclear deterrence

    Hmmm.... I've read here on PDF hundreds of times that China is a peaceful nation without territorial ambitions, and simply wants to live in peace with neighbors. So which is it?

    Aircraft Efficiency and effectiveness

    ALL jet aircraft receive a large number of maintenance man-hours relative to flight hours. It is the nature of the beast. But this report and others implies that the jet goes up for one hour, then 30 men must swarm all over it for an hour, before it is allowed to fly again. It doesn't work...

    17 Years Pakistani Student Invents, cheapest Way to Produce Electricity

    The sad reality is that no teen anywhere, regardless of their brilliance, is going to come up with an earth-changing theory that was somehow missed by PHD's with giant research teams and millions of dollars available for research. Such scenarios make for a good TV movie but don't happen in real...

    SeaWorld sued over 'enslaved' killer whales

    PETA = lunacy, detachment from reality. We can all agree that animals should be properly treated and slaughtered mercifully for food. But to declare them "people?" That would force everyone to become vegetarians. All pets would be prohibited. They are animals. We are people. There is a...

    Car running on water invented by a Pakistani

    Some people need to brush up on chemistry and thermodynamics. These are immutable laws that simply cannot be broken. There is no way to chemically extract energy from plain water. Hydrolysis of water to H2 and O2 will always require MORE energy to split the molecules than you'd get by...

    German reporter discloses Iranian brutality

    Well spoken. A beautiful, culturally advanced philosophy.

    MISSILE, ROCKET, CANNON, GUN all are invented by Chinese

    Missile NOT invented by China. It's cool to be enthused about your heritage. It's not cool to false-flag your identity. No everyday American would gush on and on about China as you do. One thing China failed at was the industrial revolution. This was uniquely European, and caused a total...

    Transition to US colonial rule: Delay by US peacekeeping force to stop the

    Darn it. You have seen through our carefully crafted plan for world colonial oppression by U.S. based Whitey. I guess we'll have to cancel it now. ---------- Post added at 09:57 AM ---------- Previous post was at 09:54 AM ---------- I'd like to ask guys like Mr. Bharat... if the USA really...

    Amazing Gyrocopter ( Helicopter ) - Made in Pakistan

    Gyrocopters are cool... I wouldn't mind owning one. But they have some treacherous tendencies that can kill you. They are not as benign and simple as they look. But they have potential uses for spotting and possibly liason work in a low-intensity conflict. They cannot hover, and do require...

    American Football

    The team on offense gets 4 chances to move the ball 10 yards. If they cross the 10 yard mark, they get a NEW set of 4 chances. Those are called "downs." First, second, third, fourth. If they reach the end zone, they get 6 points, with a kick afterward adding a point. If they can't make it...

    What's your avatar & why ...who's got the best avatar on PDF

    Snoopy with a machine gun - what's not to like? The comic was written back in a different era. The gist of the panel was something like Linus - "Charlie Brown, don't you worry about burglars and stuff at night?" C.B. - "No, I have a good watch dog." Cut to the third panel, and there's...

    Options for Pakistan in dealing with Ind, US

    It's likely with both. Politicians generally give the order, but that requires the military to carry it out. Somewhere within that chain of command will hopefully be somebody who simply says "no", assuming the launch order is invalid. The military in theory could initiate a launch, but again...

    China's 294 megatons of thermonuclear deterrence

    The nuclear keys and codes are extensive and designed to prevent exactly what you describe. Assume for a moment a nuclear weapon appeared in my garage like magic. I couldn't make it explode. No way. The act of taking it apart to remove the safeguards would also render it inoperative. I'd...

    Options for Pakistan in dealing with Ind, US

    Hope and pray that leaders remain rational and open to logic. A nuclear exchange is the ultimate illogical act. I also think it is critically important that India and Pakistan have a form of instant communication... the "red telephone" sitting on leaders' desks. If you combine level headed...

    RAW's Trafficking of Indian Children To Israel To Be Used As Food

    Guys, the truly sad thing about this scenario, about writings like this, is that there are legitimate concerns, legitimate abuses, in geopolitics today. Why worry about international aggression, trade relations, REAL human suffering, when we can focus on ludicrous and sensationalistic articles...

    Stingers in Afghanistan

    I love it how people who don't have a clue about the U.S. political system make such broad comments. I don't even pretend to know Canadian, let alone Pakistani politics, which is why I don't comment on those political systems. But so many people repeat the mantra "Joos run the U.S.", that it...

    Can You Believe It:---A self guided Bullet

    I understand what you are saying, but having an assistant track a guy with a laser from 1 mile by itself is going to be almost impossible. Even with superb optics. My impression was that the laser designator would be close than the shooter. And if he's close, he may as well shoot the guy...

    China's 294 megatons of thermonuclear deterrence

    A rational nation does not allow any single person, regardless of posting or position, to turn the nuclear key. If some rogue U.S. President decided to nuke Russia with no provocation, no logical reason, just because he's nuts, the order would not be obeyed.

    US Navy Demos 33 MJoule Railgun

    No, unless the range is very close. Mach 1 is about 8 miles per minute. Mach 11 would be 88 miles per minute, or 1.4 miles per second. Consider a jet that flies at mach 1, it's definitely going to move a large distance before a mach 11 projectile reaches it.
