1) Hezbollah provided training to Al-Qaeda in the early 1990s, making Hezbollah more knowledgeable about terrorism than Al-Qaeda. 2) The two groups had a relationship where Al-Qaeda provided money and fighters to Hezbollah, while Hezbollah provided weapons and expertise to Al-Qaeda. 3) However, Hezbollah does not want Al-Qaeda to become as knowledgeable as it is, since the Sunni Al-Qaeda and Shia Hezbollah/Iran compete for influence in the Muslim world.

1. Hezbollah VS Al-Qaeda
A very nice article from the National Review, about the love and hate
relationship between Al-Qaeda and Hezbollah. See “Al-Qaeda VS
Hezbollah”, June 2013. According to the Bush administration was
considering the members of Hezbollah as class A terrorists, while they
members of Al-Qaeda as class B terrorists.

2. It is very normal for Hezbollah terrorists to be class A terrorists and for
members of Al-Qaeda to be class B terrorists, because it was Hezbollah that
trained Al-Qaeda in the early 90s in Lebanese and Sudanese camps. See
“The Hezbollah-Al Qaeda Axis”.
And without the expertise of Hezbollah and Iran the Saudis would have not
been able to carry out the attack at the Twin Towers, because neither the
Saudi nor the Pakistani government would have been willing to whole
heartedly embrace this attack, due to their relation with the US.
On the other hand Iran and Hezbollah would not want Al-Qaeda to obtain
Hezbollah’s level of expertise, because the Sunnis of Al-Qaeda and the Shia
of Hezbollah and Iran are fighting each other for influence in the Muslim
World.
Al-Qaeda was giving Hezbollah money and fighters, both of which Al-
Qaeda had in abundance, and Hezbollah was giving Al-Qaeda weapons and
technical expertise, both of which Hezbollah had in abundance.
Therefore to say that Hezbollah people are class A terrorists and Al-Qaeda
people are class B terrorists it is like saying that the teacher is more
knowledgeable than the student. And I do not think the student can become
more knowledgeable than the teacher when it comes to terrorism, especially
if the teacher does not want that to happen. And Hezbollah does not want
that to happen with its Al-Qaeda students.

3. For the Al-Qaeda people to become equally knowledgeable with Hezbollah,
either Turkey or Pakistan should fully support them and train them, like Iran
is doing with Hezbollah, and that’s not possible at the moment.
Obviously Iran can support Al-Qaeda in order to attack the US and the Saudi
King, but there is a limit to the support the Iranians can provide to Al-Qaeda.
That’s why now that US and Iran have reached an agreement Al-Qaeda no
longer has the capabilities to carry out the spectacular attacks of the past.
If there is a definite split between the US and Pakistan, Pakistan might
support Al-Qaeda against the Americans in Afghanistan, instead of
providing Al-Qaeda with some indirect and limited support through its
support to the Taliban.
The article also mentions Hezbollah impressive presence in Latin America,
and it also says that Al-Qaeda affiliate in Syria i.e. al Nusra, is the strongest
rival of Bashar al Assad. Note the ISIS was fighting the Syrian Kurds and
not Assad. Next to Assad in Syria is the Free Syrian Army, and the men of al
Nusra and the Free Syrian Army are communicating vessels. That’s why the
American General Petreaus said that NATO has to cooperate with Al-Qaeda
against ISIS in Syria.
The article also says that the subsidiaries of Al-Qaeda in Africa attack
France, and I am sure they do so with the whole hearted support of Iran and
Hezbollah, and until recently with the support of Sudan too. Iran and Turkey
are rivals of France. France is an ally of Saudi Arabia.

4. Remember that the Arabs and the Israelis were counting on the French to
block the agreement for Iran’s nuclear program, because France is fighting
Iran for the uranium of Africa. But the deal was not blocked in the end
because the Obama administration really wanted it.
A difference between Al-Qaeda and Hezbollah is that Hezbollah is a solid
organization, while Al-Qaeda is a loose sum of Sunni gangs in various
countries. As long as bin Laden was alive there was a central command for
Al-Qaeda, and the rest was in the form of franchising. But after bin Laden’s
death it is possible that the connection between Al-Qaeda groups has
become more loose than before.
That’s why there are no contradictions on the way Hezbollah is moving,
while in Al-Qaeda some gangs move in opposite direction from other gangs,
and the Al-Qaeda members do not even agree on whether the group should
focus on Muslim apostates (Saudi King, Egyptian President etc) or on the
Crusaders (NATO).
