1. For me, she is still looks like Asian, maybe she is half asian & half white, I dunno
2. Already answered by someone before my post, president have speech in university
3. Please take a note, BSAA is not government organization, and the incident in Tall Oaks are denied to handle by BSAA because US government do not allowed it. Chris's amnesia because he want try to forget the tragedy of his teammate, there is a file about that :
CHRIS' AMNESIA
Chris Redfield suffered post-traumatic amnesia after he and his team were caught in a trap sprung by Ada Wong in the Republic of Edonia. Most of his team died, and an unconscious Chris was brought to a local hospital.
Upon waking up, Chris had no recollection of who he was or what had occurred, but his mind was wracked by an overwhelming and inexplicable guilt. Chris determined to run away, and he left the hospital before anyone could check in on him.
Until Piers Nivans and the BSAA found him, Chris lived as a moody and violent drunk, hoping that he could numb himself to the pain of what happened that fateful day.
4. I think it's his mother surname.
5. Capcom still need use of Helena is future RE, that's way they make her age as young as possible although as secret service it's ridiculous. Don't you know Helena is former CIA agent who failed to join DSO (Leon's organization) because she have emotional's issue but in RE6 ending, she join the team. (funny she can get pass the trial, but Capcom always typical abut non sense things.
6. Simmons is a national security advisor to the US president, I think it's give him high salary. And about "The Family" things, here's the explanation from file : major spoiler, highlight to view
THE FAMILY
The Family is a giant organization led by Derek C. Simmons.
This organization was founded by the Simmons family before the founding of the United States and has manipulated history since ancient times using its global network and tremendous financial power.
The Family's purpose is to maintain "global stability." In other words, a "global situation most beneficial for The Family", and they will do anything in order to achieve this purpose and maintain it.
The Family believes that "making the United States the peak of the pyramid of power" is the best endeavor for "stability." Therefore, fearing the collapse of this structure due to the exposure of the Raccoon incident, they caused bioterrorism under Simmons' orders and assassinated the President.
After the Tall Oaks incident, instructions Simmons sent to The Family were contained in the data Ada gave to Leon.
---
"The assassination of the President was a success. The Lepotitsas we deployed in Tall Oaks are unnecessary.
Begin the self-destruct program immediately. After that, begin preparations for the Tall Oaks Sterilization Operation."
"Leon S. Kennedy and Helena Harper survived and are now heading to China in pursuit of me.
A report of their deaths came out of FOS, but it was misinformation.
Immediately locate the plane Leon and Helena boarded and plant a Lepotitsa there.
We will bury the two of them with absolute certainty"

It's not Carla's intention to look likes Ada, it's Simmons who tricked her. And Carla want to revenge on Simmons for ruin her life but ended up crazy & want to revenge on everyone else & create her own world
