  Probably mainly because there haven't been any major Islamist terror attacks lately, while our attention has been drawn away by all the other scary stuff happening.  Also Al Qaeda and ISIS are only a shadow of their former selves by now.
context: It still is. For example, the Wikipedia main page for today says:
  
  A suicide bombing in a mosque in Peshawar, Pakistan, kills 100 people and injures more than 220 others. >
  
  There’s your answer. The Taliban have returned to their roots. Terrorizing their geographic locals. >
  
  ISIS is now only a shell of what it was before. After government forces recaptured Mosul, that was pretty much its last stand. It became relegated to being tiny and extremely demoralized fighting cells in the desert. Less war like conditions now and therefore less people being displaced. Many of the people who went there to fight with ISIS have become disillusioned after seeing ISIS for what it was. They are either being prosecuted in their home countries or rendered stateless after leaders of various countries have revoked their citizenships. 
  Today, Iraq has entered a period of relative stability after ISIS had been significantly weakened and US forces being ejected by the Iraqi government. Syrians are still leaving Assad's regime, albeit at smaller numbers than before. Boko Haram's leader has been killed and its camps have been destroyed.
  A huge but here... Al-Shabaab is still a major concern but more as a domestic concern. Every year, there are several attacks in Mogadishu and other cities throughout Somalia. >
  
  I would add that a group of militants attacks Southern Tanzania and northern Mozambique. >
  
  I'm actually not sure they are gone but they're definitely in retreat. USA and friends capped a lot of their leadership. They're either in retreat and rebuilding, or just done. I can't answer for Europe but I can also say that the focus in the USA is shifting to domestic terror.
  Sorry if my response is too brief. I don't believe the answers are that complex. Religious government is on the rise, authoritarianism also, so they're busy at home. Oppressing the women. >
  
  I believe this is what it is too. Focus has shifted. >
  
  It's a problem, just not as much of a problem in the West.
  The biggest potential threat for Islamist (not Islamic, there's a difference) terrorism in the west post-9/11 was almost always "lone wolf" attacks against soft targets.
  Well, the decisive action against ISIS/ISIL, Al Qaeda, and similar organizations both crippled their ability to fund such operations, diminished their reach via social media, and severely crippled their leadership structures. After all, nobody wants to take an afternoon drive and get hit with a slap chop missile that doesn't leave enough left to fill a doggy bag. >

  I'd edit that to the US, not the west. Europe has issues still, though they are less than years past as we have mostly destroyed the large organizations. >
  
  Because ISIS was destroyed. Tens of thousands of its fighters were annihilated. And more importantly, Saudi Arabia and the gulf states which exported fundamentalist Islamism are moderating a bit. 
  It’s still a major problem though, just not in the West. The Sahel for instance is constantly ravaged by Islamist violence and there was just recently a massive terror attack in Pakistan.
