In fact, since February this year, the EU has eased sanctions on Syria - for the first time in 14 years. The EU said it would maintain sanctions against individuals closely linked to the regime of former Syrian President Bashir al-Assad.
The basic purpose of the US and EU for this move is the same. Both treat the new regime in Syria differently from the Taliban regime in Afghanistan. Both appear to believe that the Taliban is not willing to change in nature, so they should still maintain the Taliban sanctions policy.
Meanwhile, the new polity in Syria is still very young and has immediately manifesting the desire to be close to the West, the gap from Russia and Iran. The United States and the EU want to encourage this tendency to use quickly lifting sanctions policies that are applied to Syria to hold the new regime in Syria that continues to lean towards the West to create more than Iran and Russia. The goal is to gradually become a new US and EU ally in dealing with Iran in the Middle East, North Africa and the Gulf, as well as to repel Russia's influence out of this area.
It can be seen that the EU and the US are no different from playing blind gambling when investing in the future, it is not known what it will be like in Syria. The reason is that there are still too many risks to politics, society, security and stability in Syria. No one is sure that the new regime in Syria will be stable for a long time when the risk of civil war is always there, which this regime has not been able to control so far.
The US and EU are well aware of these risks. But perhaps they also know that, to play big in Syria for now and in the long term, they have to accept great risks.
