A resident of Tianjin, China, said the force of an explosion there resembled a nuclear blast in its ferocity.  The blasts, “one of which was the equivalent of more than 20 tons of TNT exploding… rocked the port Wednesday night…”  One immense explosion may have been not nuclear in origin, but caused by a thermobaric weapon.
A thermobaric weapon, also called a “fuel-air explosive”, is a type of explosive that utilizes oxygen from the surrounding air to generate an intense, high-temperature explosion. Thermobaric weapons are almost 100 percent fuel, so thermobaric weapons are significantly more energetic than conventional condensed explosives of equal weight.  A fuel-air explosive has two phases: (1) Primary explosion: a fine aerosol mist of highly explosive chemical mixture; (2) Secondary explosion: the dispersed mist from the primary explosion is ignited.  In the video clip hopefully embedded below, you can see for yourself the two phases in one of the Tianjin blasts.
There are many different types of thermobaric weapons rounds that can be fitted to hand-held launchers.  So the source of the Tianjin explosion need not have been, as one commentator surmised, a shipping container filled with explosives offloaded from a ship, left on the dock, then remotely detonated. 
“As with any major event, conspiracy theories are likely to arise,” wrote Mick West when he initiated discussion on any possible conspiracy connected with the Tianjin blasts. “I anticipate people will tie this to the recent devaluation of the Chinese Yuan – suggesting China is being punished for that move.” 
It is an uncanny coincidence how China made a surprise yuan devaluation on August 11th, followed by a further surprise devaluation on August 12th, and then on or about that same day a massive blast hit Tianjin, China.
The possible thermobaric device was ignited at a warehouse storing toxic chemicals.  Release of the stored chemicals would serve as a mask for any evidence that a fuel-air explosive had been used. Add to that that the location was not as densely populated as the adjoining city area, and you have a “perfect target” for anyone wanting to “send a message” about the yuan devaluations.
China is tight-lipped, in oriental fashion, about what happened in Tianjin. But beneath the inscrutable face of Asia could lie plans to retaliate in some fashion. Two seven-year cycles figure in to all this: (1) the 2×7 equals 14-years since the surreal events of September 11, 2001, a.k.a., “9/11”; and (2) the seven years since the “Federal Reserve” put a key interest rate at near-zero percent and has kept it there ever since. (Further background: Where Have You Gone, Abby Martin?, Ersjdamoo’s Blog, August 13, 2015.)
Will the “Federal Reserve” be slowly hiking interest rates beginning around mid-September 2015? Prognostications have been varying about this question. Any use of a thermobaric bomb in Tianjin would give an added nuance to the term “currency wars.” A “tough guy” stance now could be involved. The “Fed”, consequent to the surprise yuan devaluation, must now hike rates, says one Joel Naroff. If the “Fed” does not hike rates in September, it will seem like the U.S. has turned “yellow” and is led by Yellow Yellen (Janet Yellen), poster girl for whomever really runs the “Federal Reserve.” 
China’s shock move to devalue the yuan risks opening a new front in a currency war that stretches from the euro zone to Japan, says Stephen Roach, a senior fellow at Yale University and former Morgan Stanley non-executive chairman in Asia. Dollar strength consequent to the surprise yuan devaluation now casts doubt over whether the “Fed” will still go ahead with tightening in 2015. 
So it is up for grabs. Will Yellen turn “yellow” and delay an anticipated September rate increase? Or will the “Fed” decide to say, “Damn the torpedoes! Full speed ahead!” and begin to raise rates? And what if the Tianjin blast was in fact caused by a thermobaric bomb? If China secretly retaliates, how would that affect an interest rate decision? You won’t want to miss forthcoming episodes of Yellen at Little Bighorn.
