This media told you own version, other medias told you another one. We never get the truth, pal.
No? you can use your better judgement and brain to discern fact from fiction. Here is my line of thought, feel free to correct me:
The Russian version: Syrian army airstrike attacked a terrorist warehouse which contained "toxic substances" unbeknownst to them, with the explosion causing it to spread.
The UN/West version: Syrian army airstrike spread sarin nerve gas/a mix of toxic substances over the population.
CAPABILITY
I believe it is much more plausible that the Syrian regime is capable to perform this attack. It has considerable technological superiority over the opposition, including a center for technological/chemical studies which is active since the early seventies -
the SSRC. Synthesizing and storing nerve agents is a difficult and dangerous, and can't be done by just anyone - especially not relatively disorganized opposition groups which have no practical knowledge in chemical warfare. Compare that to the Syrian regime
which has declared to have chemical weapons stockpiled.
Furthermore, as stated in my previous source, sarin is unstable and is synthesized only hours or days before it is used from two more stable components. This means that the Syrian regime either knew the opposition uses chemical weapons and did not report this for a lot of political gain, or just happened to attack at the right time at the right place - highly unlikely.
Also, even if the opposition is able to create it, they have no effective method of delivering it, as they have no long range missiles or planes. This is chemical weapon,
you can't just put it on a mortar and shoot. This also means that if you happen to bomb canisters of it, most of the substance will stay in the building as long as the building has walls.
This leads me to conclude that the Syrian army is capable of attacking with sarin gas while the opposition is not.
REASON
According to some participants in this thread, this is actually a false flag operation. Note that this is not the Russian version, which is why I'll disregard it, as both official sides do not take this stand. In any case I will restate that I think it is a laughable idea to think the opposition bombed it's own supporters with chemical weapons for the slim possibilities of gaining some aid and sympathy from the west.
If we take the facts about sarin manufacturing, we come to the conclusion that the opposition was about to attack the regime with sarin in a matter of days, how would they get from where the attack was to the part of regime control Damascus is unknown, but again, this is not a substance that can be easily moved without extreme danger, especially across multiple warfields and danger zones. The other option is that the opposition for some reason decided to create the gas and store it in its unstable form, which is the equivalent of removing the safety from a grenade stored in your room then going to sleep.
The rebels, however, claim this is another attempt by the regime to bring east Ghouta (where the chemicals were released) to independent peace negotiations - removing the rebels and becoming part of the regime again for peace. This city has been a thorn at the side of Damascus since 2013, and they are trying very hard to
make the population there abandon the opposition. I know bombing with chemical weapons to make the population turn against the opposition sounds wrong, but this sort of thing worked in Aleppo - the regime cracked down on the city killing thousands with non-chemical weapons until they gave up. The regime wants to break the fighting spirit of both the opposition and its supporting population.
REPERCUSSIONS
Some thread participants rightfully claimed that the regime would not attack with chemical weapons because of the repercussions. However, the last attack in 2013 had virtually zero repercussions on the regime. Assad vowed to destroy his chemical weapon stockpiles, and that's about it. With the UN paralyzed by Russian vetoes, Europe crippled by a wave of oncoming elections, and confused over ISIS and the refugee crisis, and the US with a president which is clearly not interested in foreign policy ("
America first"), the possibility of worldwide repercussions is extremely slim.
I would like to read your line of reasoning as to how and why this attack was not done by the regime.
