ISRO scientists challenges the claims of NASA's statement on Mission Shakti

NASA has strongly flayed Mission Shakti, India's anti-satellite (ASAT) weapon test, saying the debris from the outburst endangers the International Space Station (ISS). 
"What we are apprehending right now, objects big enough to trail – like we can’t track 10 centimeters or bigger — about 60 pieces have been tracked," Jim Bridenstine, the administrator of NASA said in a briefing to his employees.
According to NASA, the danger of collision of the debris with the International Space Station (ISS) has raised by 44% over the last 10 days. This may put India's alliance with the US on Mission Gaganyaan, the Indian human spaceflight programme, in trouble. 
It may also push India towards cementing its association with Russia for the Gaganyaan mission.
India and France have already marked a memorandum of understanding where the French scientists will share their specialization to help the human space project get off the ground.
Is there really a threat to the ISS?
The United States Air Force (USAF) has also been tracking fragments from India's ASAT test. Lt. Gen. David Thompson, vice commander of USAF reported the Senate Armed Services Committee in the US that, "they are following about 270 different objects in the debris field." Adding that the number will only increase as the debris spreads out and their sensors pick up more information.
The Indian government, on the other hand, is challenging that their test was conducted in low Earth orbit (LEO) in order to ensure that there is no space debris formed. And whatever debris may have been left behind, will eventually be crumbled and fall back onto Earth within the span of a few weeks.
Experts like Kumar Abhijeet, a member of the International Institute of Space Law, also concluded that the debris will most likely dissipate in the atmosphere.
While China's ASAT test in 2007 might have culminated in the demolition of two Russian satellites due to the debris left behind, the test was also conducted at a higher altitude of 850 kilometers. India's test, on the other hand, was at the height of 300kms.
Since it well below the 400 km threshold, most experts believed that there is no threat to the ISS especially since the debris from the 2008 test conducted by the US at 250kms dissipated within days.
Friends, please share your opinions about NASA's statement.
